LM4132, LM4132-Q1 SOT-23 Precision Low Dropout Voltage Reference
1 Features
3 Description
The LM4132 family of precision voltage references
performs comparable to the best laser-trimmed
bipolar references, but in cost-effective CMOS
technology. The key to this breakthrough is the use of
EEPROM registers for correction of curvature,
temperature coefficient (tempco), and accuracy on a
CMOS band-gap architecture allowing package-level
programming to overcome assembly shift. The shifts
in voltage accuracy and tempco during assembly of
die into plastic packages limit the accuracy of
references trimmed with laser techniques.

Output Initial Voltage Accuracy: 0.05%
Low Temperature Coefficient: 10 ppm/°C
Low Supply Current: 60 µA
Enable Pin Allowing a 3-µA Shutdown Mode
20-mA Output Current
Unlike other LDO references, the LM4132 can deliver
up to 20 mA and does not require an output capacitor
or buffer amplifier. These advantages along with the
SOT-23 packaging are important for space-critical
applications.
Voltage Options: 1.8 V, 2.048 V, 2.5 V, 3 V,
3.3 V, 4.096 V
•
Custom Voltage Options Available
(1.8 V to 4.096 V)
Series references provide lower power consumption
than shunt references, because they do not have to
idle the maximum possible load current under no-load
conditions. This advantage, the low quiescent current
(60 µA), and the low dropout voltage (400 mV) make
the LM4132 ideal for battery-powered solutions.
•
•
VIN Range of VREF + 400 mV to 5.5 V at 10 mA
Stable With Low-ESR Ceramic Capacitors
2 Applications
The LM4132 is available in five grades (A, B, C, D
and E) for greater flexibility. The best grade devices
(A) have an initial accuracy of 0.05% with a specified
temperature coefficient of 10 ppm/°C or less, while
the lowest grade devices (E) have an initial accuracy
of 0.5% and a tempco of 30 ppm/°C.

(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) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by TJMAX
(maximum junction temperature), RθJA (junction to ambient thermal resistance) and TA (ambient temperature). The maximum power
dissipation at any temperature is: PDissMAX = (TJMAX – TA) / RθJA up to the value listed in theAbsolute Maximum Ratings. RθJA for SOT-23
is 164.1°C/W, TJMAX = 125°C.

(1) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using
Statistical Quality Control.
(2) Typical numbers are at 25°C and represent the most likely parametric norm.
(3) Long-term stability is VREF at 25°C measured during 1000 hrs.
(4) Thermal hysteresis is defined as the change in 25°C output voltage before and after cycling the device from (–40°C to 125°C).
(5) Dropout voltage is defined as the minimum input to output differential at which the output voltage drops by 0.5% below the value
measured with a 5-V input.

7 Detailed Description
7.1 Overview
The LM4132 device is a precision band-gap voltage reference available in 6 different voltages with 20-mA
current source capability. This series reference can operate with input voltages from VREF + 400 mV to 5.5 V
while consuming 60-µA (typical) supply current. In shutdown mode, current drops to 3 µA (typical). The LM4132
is available in five grades from A and E.
The best grade devices (A) have an initial accuracy of 0.05% with a specified tempco of 10 ppm/°C from –40°C
to 125°C. The grade devices (E) have an initial accuracy of 0.5% with specified tempco of 30 ppm/°C from –40°C
to 125°C.

7.3 Feature Description
The LM4132 can be remotely operated by applying an EN voltage between 65% of VIN, and VIN. The LM4312
can be remotely disabled by applying an EN voltage between 0 V to 35% of VIN. The EN pin can also be
strapped to VIN, so VREF is active when VIN is applied.
7.3.1 Short Circuited Output
The LM4132 features indefinite short-circuit protection. This protection limits the output current to 75 mA when
the output is shorted to ground.
7.3.2 Turnon Time
Turnon time is defined as the time taken for the output voltage to rise to 90% of the preset value. The turnon time
depends on the load. The turnon time is typically 33.2 µs when driving a 1-µF load and 78.8 µs when driving a
10-µF load. Some users may experience an extended turnon time (up to 10 ms) under brownout conditions and
low temperatures (–40°C).

7.3.3 Thermal Hysteresis
Thermal hysteresis is defined as the change in output voltage at 25ºC after some deviation from 25ºC. This is to
say that thermal hysteresis is the difference in output voltage between two points in a given temperature profile.
An illustrative temperature profile is shown in Figure 47.

8 Applications 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 LM4132 family of precision voltage references can deliver up to 20 mA without an output capacitor or buffer
amplifier. The LM4132 is ideal for battery-powered solutions, with a low quiescent current of 60 µA, and a low
dropout voltage of 400 mV. The LM4132 enters the shutdown mode (3 µA, typical) when EN is 0 V.

8.2.1.1 Design Requirements
For this design example, use the parameters listed as the input parameters.
•
•
•
VIN > VREF + 400 mV (ILOAD ≤ 10 mA)
LOAD ≤ 20 mA
The LM4132 is enabled when 65%VIN< VEN ≤ VIN. VEN cannot be greater than VIN; otherwise, the device does
I
not operate correctly.
•
The devices is disabled when 0 V ≤ VEN ≤ 35% VIN.
8.2.1.2 Detailed Design Procedure
The foundation of any voltage reference is the band-gap circuit. While the reference in the LM4132 is developed
from the gate-source voltage of transistors in the device, principles of the band-gap circuit are easily understood
using a bipolar example. For a detailed analysis of the bipolar band-gap circuit, refer to AN-56 LM113 1.2V
Reference (SNVA514).
8.2.1.2.1 Supply and Enable Voltages
To ensure proper operation, VEN and VIN must be within a specified range. An acceptable range of input voltages
is calculated by Equation 2:
VIN > VREF + 400 mV (ILOAD ≤ 10 mA)
(2)
The EN pin uses an internal pullup current source (IPULLUP ≊ 2 µA) that may be left floating or triggered by an
external source. If the device is not enabled by an external source, it may be connected to VIN. An acceptable
range of enable voltages is given by Figure 4. See Electrical Characteristics LM4132-1.8 (VOUT = 1.8 V) and
Figure 3 for more detail. The device does not operate correctly for VEN > VIN.

Typical Applications (continued)
8.2.1.2.2 Component Selection
A small ceramic (X5R or X7R) capacitor on the input must be used to ensure stable operation. The value of CIN
must be sized according to the output capacitor value. The value of CIN must satisfy the relationship CIN ≥ COUT
.
When no output capacitor is used, CIN must have a minimum value of 0.1 µF. Noise on the power-supply input
may affect the output noise. Larger input capacitor values (typically 4.7 µF to 22 µF) may help reduce noise on
the output and significantly reduce overshoot during start-up. Use of an additional optional bypass capacitor from
the input and ground may help further reduce noise on the output. With an input capacitor, the LM4132 drives
any combination of resistance and capacitance up to VREF / 20 mA and 10 µF, respectively.
The LM4132 is designed to operate with or without an output capacitor and is stable with capacitive loads up to
10 µF. Connecting a capacitor from the output and ground significantly improves the load transient response
when switching from a light load to a heavy load. The output capacitor must not be made arbitrarily large
because capacitor selection affects the turnon time as well as line and load transients.
While a variety of capacitor chemistry types may be used, it is typically advisable to use low equivalent series
resistance (ESR) ceramic capacitors. Such capacitors provide a low impedance to high frequency signals,
effectively bypassing them to ground. Bypass capacitors must be mounted close to the device. Mounting bypass
capacitors close to the device helps reduce the parasitic trace components thereby improving performance.
8.2.1.2.3 Temperature Coefficient
Temperature drift is defined as the maximum deviation in output voltage over the operating temperature range.
This deviation over temperature may be shown in Figure 48:
Voltage
V
REF_MAX
Temperature
V
REF_MIN
Temperature Range
Figure 48. VREF vs Temperature Profile
Temperature coefficient may be expressed analytically as Equation 3:
(VREF_MAX - VREF_MIN
)
x 106 ppm
TD
=
VREF x ΔT
where
•
•
•
•
•
•
TD = Temperature drift
VREF = Nominal preset output voltage
VREF_MIN = Minimum output voltage over operating temperature range
VREF_MAX = Maximum output voltage over operating temperature range
ΔT = Operating temperature range
The LM4132 features a low temperature drift of 10 ppm (maximum) to 30 ppm (maximum), depending on the
grade.
(3)
8.2.1.2.4 Long-Term Stability
Long-term stability refers to the fluctuation in output voltage over a long period of time (1000 hours). The LM4132
features a typical long-term stability of 50 ppm over 1000 hours. The measurements are made using 5 units of
each voltage option, at a nominal input voltage (5 V), with no load, at room temperature.

10 Layout
10.1 Layout Guidelines
The mechanical stress due to PCB mounting can cause the output voltage to shift from its initial value. The
center of a PCB generally has the highest mechanical and thermal expansion stress. Mounting the device near
the edges or the corners of the board where mechanical stress is at its minimum. References in SOT-23
packages are generally less prone to assembly stress than devices in small outline (SOIC) packages.
A mechanical isolation of the device by creating an island by cutting a U shape slot (U - SLOT) on the PCB while
mounting the device helps in reducing the impact of the PCB stresses on the output voltage of the reference.
This approach would also provide some thermal isolation from the rest of the circuit.
Figure 54 shows a recommended printed board layout for LM4132 along with an in-set diagram, which exhibits a
slot cut on three sides of the reference device.
Bypass capacitors must be mounted close to the device. Mounting bypass capacitors close to the device reduces
the parasitic trace components, thereby improving performance.

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.
