LP5952 350-mA Dual-Rail Linear Regulator  
1 Features  
3 Description  
The LP5952 is a dual-supply-rail linear regulator  
optimized for powering ultralow-voltage circuits from a  
single Li-Ion cell or 3-cell NiMH/NiCd battery.  
1
Input Voltage Range: 0.7 V to 4.5 V  
2.5 V VBATT 5.5 V  
0.5V VOUT 2 V  
In the typical post-regulation application VBATT is  
directly connected to the battery (range 2.5 V to  
5.5 V), and VIN is supplied by the output voltage of  
the DC-DC converter (range 0.7 V to 4.5 V).  
Ensured 350-mA Output Current  
For ILOAD = 350 mA:  
V
BATT VOUT(NOM) + 1.5 V or 2.5 V  
(Whichever is Higher)  
For ILOAD = 150 mA:  
BATT VOUT(NOM) + 1.3 V or 2.5 V  
(Whichever is Higher)  
The device offers superior dropout and transient  
features combined with very low quiescent currents.  
In shutdown mode (Enable (EN) pin pulled low) the  
device turns off and reduces battery consumption to  
0.1 µA (typical). The LP5952 also features internal  
protection against overtemperature, overcurrent, and  
undervoltage conditions.

Depending upon application, only one or two tiny  
surface-mount external components are required;  
performance is specified for a –40°C to +125°C  
junction temperature range. The device is available in  
fixed output voltages from 0.5 V to 2 V. For  
availability, please contact your local Texas  
Instruments sales office.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings  
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended  
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.  
(2) All voltages are with respect to the potential at the GND pin.  
(3) If Military or Aerospace specified devices are required, contact Texas Instruments Sales Office or Distributors for availability and  
specifications.  
(4) Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at TJ = 165°C (typical) and  
disengages at TJ = 145°C (typical).

(1) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may  
have to be derated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX-OP  
=
125°C), the maximum power dissipation of the device in the application (PD-MAX), and the junction-to ambient thermal resistance of the  
part/package in the application (RθJA), as given by: TA-MAX = TJ-MAX-OP – (RθJA × PD-MAX).

(4) The capacitor tolerance should be 30% or better over temperature. The full operating conditions for the application should be considered  
when selecting a suitable capacitor to ensure that the minimum value of capacitance is always met. Recommended capacitor type is  
X7R. However, dependent on application, X5R, Y5V, and Z5U can also be used. The shown minimum limit represents real minimum  
capacitance, including all tolerances and must be maintained over temperature and DC bias voltage (See Detailed Design Procedure in  
Application and Implementation.)

7 Detailed Description  
7.1 Overview  
The LP5952 is a dual-supply-rail linear regulator optimized for powering ultralow-voltage circuits from a single Li-  
Ion cell or 3 cell NiMH/NiCd batteries. In a typical application, BATT is connected to the battery, and IN can be  
supplied by the output of front stage DC-DC Converter. IN does not exceed BATT at any time.

7.3 Feature Description  
7.3.1 Dual-Rail Supply  
The LP5952 requires two different supply voltages:  
VIN, the power input voltage, is regulated to the fixed output voltage.  
VBATT, the bias input voltage, supplies internal circuitry.  
It is important that VIN does not exceed VBATT at any time. If the device is used in the typical post-regulation  
application as shown in Figure 18, the sequencing of the two power supplies is not an issue because VBATT  
supplies both the DC-DC regulator and the LP5952 device. The output voltage of the DC-DC regulator takes  
some time to rise up and supply the input voltage of the device. In this application VIN always ramps up more  
slowly than VBATT  
.
If VIN is shorted to VBATT, the voltages at the two supply pins ramp up simultaneously causing no problems.  
However, in applications with two independent supplies connected to the LP5952, special care must be taken to  
ensure that VIN is always VBATT  
.
7.3.2 No-Load Stability  
The LP5952 remains stable and in regulation with no external load. This is an important consideration in some  
circuits, for example, CMOS RAM keep-alive applications.  
7.3.3 Fast Turnon  
Fast turnon is ensured by an optimized architecture allowing a fast ramp of the output voltage to reach the target  
voltage while the inrush current is controlled low at 120 mA typical (for a COUT of 2.2 µF).

Feature Description (continued)  
7.3.4 Short-Circuit Protection  
The LP5952 is short-circuit protected and, in the event of a peak overcurrent condition, the output current  
through the NFET pass device is limited.  
If the overcurrent condition exists for a longer time, the average power dissipation increases depending on the  
input-to-output voltage difference until the thermal shutdown circuitry turns the NFET off. Refer to Power  
Dissipation and Device Operation for power dissipation calculations.  
7.3.5 Thermal-Overload Protection  
Thermal-overload protection limits the total power dissipation in the LP5952. When the junction temperature  
exceeds TJ = 165°C typical, the shutdown logic is triggered, and the NFET is turned off, allowing the device to  
cool down. After the junction temperature dropped by 20°C (temperature hysteresis) typical, the NFET is  
activated again. This results in a pulsed output voltage during continuous thermal-overload conditions.  
The thermal-overload protection is designed to protect the LP5952 in the event of a fault condition. For normal  
continuous operation, do not exceed the absolute maximum junction temperature rating of TJ = 150°C (see  
Absolute Maximum Ratings).  
7.3.6 Reverse Current Path  
The internal NFET pass device in LP5952 has an inherent parasitic body diode. During normal operation, the  
input voltage is higher than the output voltage, and the parasitic diode is reverse biased. However, if the output is  
pulled above the input in an application, the current flows from the output to the input as the parasitic diode gets  
forward biased. The output can be pulled above the input as long as the current in the parasitic diode is limited to  
50 mA. For currents above this limit an external Schottky diode must be connected from VOUT to VIN (cathode on  
VIN, anode on VOUT).  
7.4 Device Functional Modes  
7.4.1 Enable Operation  
The LP5952 may be switched to an ON or OFF state by a logic input at the EN pin, VEN. A logic high at this pin  
turns the device on. When the enable pin is low, the regulator output is off, and the device typically consumes  
0.1 µA.  
If the application does not require the enable switching feature, the EN pin must be tied to VBATT to keep the  
regulator output permanently on.  
To ensure proper operation, the signal source used to drive the EN input must be able to swing above and below  
the specified turnon and turnoff voltage thresholds shown in VIL and VIH in Electrical Characteristics: Enable  
Control.

8 Application and Implementation  
NOTE  
Information in the following applications sections is not part of the TI component  
specification, and TI does not warrant its accuracy or completeness. TI’s customers are  
responsible for determining suitability of components for their purposes. Customers should  
validate and test their design implementation to confirm system functionality.  
8.1 Application Information  
The LP5952 is designed to meet ultralow input-voltage application, by implementing VBATT as power supply of  
this device. The VBATT is connected to the battery (range 2.5 V to 5.5 V), the VIN range can be 0.7 V to 4.5 V.  
The device offers superior dropout and transient features combined with very low-quiescent currents. The  
LP5952 delivers this performance in standard packages DSBGA and USON with an operating junction  
temperature (TJ) of –40°C to +125°C.

8.2.1.2 Detailed Design Procedure  
8.2.1.2.1 External Capacitors  
As is common with most regulators, the LP5952 requires external capacitors to ensure stable operation. The  
LP5952 is specifically designed for portable applications requiring minimum board space and the smallest size  
components. These capacitors must be correctly selected for good performance.  
8.2.1.2.2 Input Capacitor  
If the LP5952 is used as a stand-alone device, an input capacitor at VIN is required for stability. It is  
recommended that a 1-µF capacitor be connected between the LP5952 power voltage IN pin and ground. (This  
capacitance value may be increased without limit).

SNVS469F OCTOBER 2006REVISED DECEMBER 2015  
This capacitor must be located a distance of not more than 1 cm from the IN pin and returned to a clean analog  
ground. Any good quality ceramic, tantalum, or film capacitor may be used at the input.  
A capacitor at VBATT is not required if the distance to the supply does not exceed 5 cm.  
If the device is used in the typical application as post regulator after a DC-DC regulator, no input capacitors are  
required — the capacitors of the DC-DC regulator (CIN and COUT) are sufficient if both components are mounted  
close to each other and a proper GND plane is used. If the distance between the output capacitor of the DC-DC  
regulator and the IN pin of the LP5952 is larger than 5 cm, adding an input capacitor at VIN is recommended.  
NOTE  
Important: Tantalum capacitors can suffer catastrophic failures due to surge current  
when connected to a low-impedance source of power (like a battery or a very large  
capacitor). If a tantalum capacitor is used at the input, it must be ensured by the  
manufacturer to have a surge current rating sufficient for the application.  
The equivalent series resistance (ESR) of the input capacitor should be in the range of 3 mto 300 m. The  
tolerance and temperature coefficient must be considered when selecting the capacitor to ensure the  
capacitance remains 470 nF over the entire operating temperature range.  
8.2.1.2.3 Output Capacitor  
The LP5952 is designed specifically to work with very small ceramic output capacitors. A ceramic capacitor  
(dielectric types X7R, Z5U, or Y5V) in the 2.2-µF range (up to 10 µF) and with an ESR between 3 mto 300 mΩ  
is suitable as COUT in the LP5952 application circuit.  
This capacitor must be located a distance of not more than 1 cm from the OUT pin and returned to a clean  
analog ground.  
It is also possible to use tantalum or film capacitors at the device output, VOUT, but these are not as attractive for  
reasons of size and cost (see Capacitor Characteristics).  
8.2.1.2.4 Capacitor Characteristics  
The LP5952 is designed to work with ceramic capacitors on the output to take advantage of the benefits they  
offer. For capacitance values in the 1-µF to 4.7-µF range, ceramic capacitors are the smallest, least expensive  
and have the lowest ESR values, thus making them best for eliminating high-frequency noise. The ESR of a  
typical 1-µF ceramic capacitor is in the range of 3 mto 40 m, which easily meets the ESR requirement for  
stability for the LP5952.  
For both input and output capacitors, careful interpretation of the capacitor specification is required to ensure  
correct device operation. The capacitor value can change greatly, depending on the operating conditions and  
capacitor type.  
In particular, the output capacitor selection must take account of all the capacitor parameters, to ensure that the  
specification is met within the application. The capacitance can vary with DC bias conditions as well as  
temperature and frequency of operation. Capacitor values show some decrease over time due to aging. The  
capacitor parameters are also dependant on the particular case size, with smaller sizes giving poorer  
performance figures in general. Figure 10 shows a typical graph comparing different capacitor case sizes in a  
capacitance vs. DC Bias plot. As shown Figure 10, increasing the DC-bias condition can result in the capacitance  
value falling below the minimum value given in Input and Output Capacitors (Recommended) (0.47 µF or 1.5 µF  
in this case). The graph shows the capacitance out of specification for the 0402 case size capacitor at higher  
bias voltages. It is therefore recommended that the capacitor-manufacturer specifications for the nominal value  
capacitor are consulted for all conditions, as some capacitor sizes (such as 0402) may not be suitable in the  
actual application.

DC BIAS (V)  
Figure 10. Typical Variation In Capacitance vs DC Bias  
Capacitance of the ceramic capacitor can vary with temperature. The capacitor type X7R, which operates over a  
temperature range of –55°C to +125°C, only varies the capacitance to within ±15%. The capacitor type X5R has  
a similar tolerance over a reduced temperature range of –55°C to +85°C. Many large value ceramic capacitors,  
larger than 1 µF, are manufactured with Z5U or Y5V temperature characteristics. Their capacitance can drop by  
more than 50% as the temperature varies from 25°C to 85°C. Therefore, X7R is recommended over Z5U and  
Y5V in applications where the ambient temperature changes significantly above or below 25°C.  
Tantalum capacitors are less desirable than ceramic for use as output capacitors because they are more  
expensive when comparing equivalent capacitance and voltage ratings in the 1-µF to 4.7-µF range.  
Another important consideration is that tantalum capacitors have higher ESR values than equivalent size  
ceramics. This means that while it may be possible to find a tantalum capacitor with an ESR value within the  
stable range, it would have to be larger in capacitance (which means bigger and more costly) than a ceramic  
capacitor with the same ESR value. The ESR of a typical tantalum increases about 2:1 as the temperature goes  
from 25°C down to –40°C, so some guard band must be allowed.  
8.2.1.2.5 Power Dissipation and Device Operation  
The permissible power dissipation for any package is a measure of the capability of the device to pass heat from  
the power source, the junctions of the device, to the ultimate heat sink, the ambient environment. Thus the power  
dissipation is dependent on the ambient temperature and the thermal resistance across the various interfaces  
between the die and ambient air.  
As stated in the Recommended Operating Conditions, the allowable power dissipation for the device in a given  
package can be calculated using Equation 1:  
PD = (TJ(MAX) – TA) / RθJA  
(1)  
With an RRθJA = 181°C/W, the device in the 5-pin DSBGA package returns a value of 552 mW with a maximum  
junction temperature of 125°C at TA of 25°C or 221 mW at TA of 85°C.  
The actual power dissipation across the device can be estimated by Equation 2:  
PD = (VIN – VOUT) × IOUT

This establishes the relationship between the power dissipation allowed due to thermal consideration, the voltage  
drop across the device, and the continuous current capability of the device. Equation 1 and Equation 2 must be  
used to determine the optimum operating conditions for the device in any application. As an example, to keep full  
load current capability of 350 mA for a 1.5-V output voltage option at a high ambient temperature of 85°C, VIN  
has to be kept 2.1 V (for DSBGA package):  
VIN PD / IOUT + VOUT = 221 mW / 350 mA + 1.5 V = 2.1 V

This device is designed to operate from an input supply voltage range of 0.7 V to 4.5 V. The input supply should  
be well regulated and free of spurious noise. A minimum capacitor value of 1-μF is required to be within 1 cm of  
the IN pin. The VBATT range is 2.5 V to 5.5 V and, in the typical application, VBATT is connected to batteries. In  
any application, VIN does not exceed VBATT

10.1 Layout Guidelines  
For best overall performance, place all circuit components on the same side of the circuit board and as near to  
the respective LDO pin connections as practical. Place ground return connections as close as possible to the  
input and output capacitor and to the LDO ground pin, connected by a wide, copper surface. The use of vias and  
long traces to create LDO circuit connection is strongly discouraged and negatively affect system performance.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance  
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may  
reference these types of products as "Pb-Free".

RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.  
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based  
flame retardants must also meet the <=1000ppm threshold requirement.  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.  
(6)  
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two  
lines if the finish value exceeds the maximum column width.
