FEATURES  
DESCRIPTION  
The LP3892 is a high current, fast response regulator  
which can maintain output voltage regulation with  
minimum input to output voltage drop. Fabricated on  
a CMOS process, the device operates from two input  
voltages: Vbias provides voltage to drive the gate of  
the N-MOS power transistor, while Vin is the input  
voltage which supplies power to the load. The use of  
an external bias rail allows the part to operate from  
ultra low Vin voltages. Unlike bipolar regulators, the  
CMOS architecture consumes extremely low  
quiescent current at any output load current. The use  
of an N-MOS power transistor results in wide  
bandwidth, yet minimum external capacitance is  
required to maintain loop stability.

(1) Absolute maximum ratings indicate limits beyond which damage to the component may occur. Operating ratings indicate conditions for  
which the device is intended to be functional, but do not ensure specific performance limits. For specifications, see Electrical  
Characteristics. Specifications do not apply when operating the device outside of its rated operating conditions.  
(2) The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin.  
(3) The machine model is a 220 pF capacitor discharged directly into each pin. The machine model ESD rating of pin 5 is 100V.  
(4) At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink thermal values.  
θJ-A for TO-220 devices is 65°C/W if no heatsink is used. If the TO-220 device is attached to a heatsink, a θJ-S value of 4°C/W can be  
assumed. θJ-A for DDPAK/TO-263 devices is approximately 40°C/W if soldered down to a copper plane which is at least 1.5 square  
inches in area. θJ-A value for typical SO PowerPAD-8 PC board mounting is 166°C/W. If power dissipation causes the junction  
temperature to exceed specified limits, the device will go into thermal shutdown.

Application Hints  
www.ti.com  
EXTERNAL CAPACITORS  
To assure regulator stability, input and output capacitors are required as shown in the Typical Application Circuit.  
OUTPUT CAPACITOR  
At least 10µF of output capacitance is required for stability (the amount of capacitance can be increased without  
limit). The output capacitor must be located less than 1 cm from the output pin of the IC and returned to a clean  
analog ground. The ESR (equivalent series resistance) of the output capacitor must be within the "stable" range  
as shown in Figure 19 over the full operating temperature range for stable operation.

LOAD CURRENT (A)  
Figure 19. Minimum ESR vs Output Load Current  
Tantalum capacitors are recommended for the output as their ESR is ideally suited to the part's requirements  
and the ESR is very stable over temperature. Aluminum electrolytics are not recommended because their ESR  
increases very rapidly at temperatures below 10°C. Aluminum caps can only be used in applications where lower  
temperature operation is not required.  
A second problem with Al caps is that many have ESR's which are only specified at low frequencies. The typical  
loop bandwidth of a linear regulator is a few hundred kHz to several MHz. If an Al cap is used for the output cap,  
it must be one whose ESR is specified at a frequency of 100 kHz or more.  
Because the ESR of ceramic capacitors is only a few milliohms, they are not suitable for use as output capacitors  
on LP389X devices. The regulator output can tolerate ceramic capacitance totaling up to 15% of the amount of  
Tantalum capacitance connected from the output to ground.  
INPUT CAPACITOR  
The input capacitor must be at least 10 µF, but can be increased without limit. It's purpose is to provide a low  
source impedance for the regulator input. Ceramic capacitors work best for this, but Tantalums are also very  
good. There is no ESR limitation on the input capacitor (the lower, the better). Aluminum electrolytics can be  
used, but their ESR increase very quickly at cold temperatures. They are not recommended for any application  
where temperatures go below about 10°C.  
BIAS CAPACITOR  
The 0.1µF capacitor on the bias line can be any good quality capacitor (ceramic is recommended).  
BIAS VOLTAGE  
The bias voltage is an external voltage rail required to get gate drive for the N-FET pass transistor. Bias voltage  
must be in the range of 4.5 - 6V to assure proper operation of the part.  
UNDER VOLTAGE LOCKOUT  
The bias voltage is monitored by a circuit which prevents the regulator output from turning on if the bias voltage  
is below approximately 4V.

SNVS236D SEPTEMBER 2003REVISED APRIL 2013  
SHUTDOWN OPERATION  
Pulling down the shutdown (S/D) pin will turn-off the regulator. Pin S/D must be actively terminated through a  
pull-up resistor (10 kto 100 k) for a proper operation. If this pin is driven from a source that actively pulls high  
and low (such as a CMOS rail to rail comparator), the pull-up resistor is not required. This pin must be tied to Vin  
if not used.  
POWER DISSIPATION/HEATSINKING  
A heatsink may be required depending on the maximum power dissipation and maximum ambient temperature of  
the application. Under all possible conditions, the junction temperature must be within the range specified under  
operating conditions. The total power dissipation of the device is given by:  
PD = (VINVOUT)IOUT+ (VIN)IGND  
(1)  
where IGND is the operating ground current of the device.  
The maximum allowable temperature rise (TRmax) depends on the maximum ambient temperature (TAmax) of the  
application, and the maximum allowable junction temperature (TJmax):  
TRmax = TJmaxTAmax  
(2)  
The maximum allowable value for junction to ambient Thermal Resistance, θJA, can be calculated using the  
formula:  
θJA = TRmax / PD  
(3)  
These parts are available in TO-220 and DDPAK/TO-263 packages. The thermal resistance depends on amount  
of copper area or heat sink, and on air flow. If the maximum allowable value of θJA calculated above is 60 °C/W  
for TO-220 package and 60 °C/W for DDPAK/TO-263 package no heatsink is needed since the package can  
dissipate enough heat to satisfy these requirements. If the value for allowable θJA falls below these limits, a heat  
sink is required.  
HEATSINKING TO-220 PACKAGE  
The thermal resistance of a TO-220 package can be reduced by attaching it to a heat sink or a copper plane on  
a PC board. If a copper plane is to be used, the values of θJA will be same as shown in next section for  
DDPAK/TO-263 package.  
The heatsink to be used in the application should have a heatsink to ambient thermal resistance, θHA≤ θJA − θCH  
− θJC.  
In this equation, θCH is the thermal resistance from the case to the surface of the heat sink and θJC is the thermal  
resistance from the junction to the surface of the case. θJC is about 3°C/W for a TO-220 package. The value for  
θCH depends on method of attachment, insulator, etc. θCH varies between 1.5°C/W to 2.5°C/W. If the exact value  
is unknown, 2°C/W can be assumed.  
HEATSINKING DDPAK/TO-263 PACKAGE  
The DDPAK/TO-263 package uses the copper plane on the PCB as a heatsink. The tab of these packages are  
soldered to the copper plane for heat sinking. The graph below shows a curve for the θJA of DDPAK/TO-263  
package for different copper area sizes, using a typical PCB with 1 ounce copper and no solder mask over the  
copper area for heat sinking.

As shown in the graph below, increasing the copper area beyond 1 square inch produces very little improvement.  
The minimum value for θJA for the DDPAK/TO-263 package mounted to a PCB is 32°C/W.  
Figure 22 shows the maximum allowable power dissipation for DDPAK/TO-263 packages for different ambient  
temperatures, assuming θJA is 35°C/W and the maximum junction temperature is 125°C.  
Figure 21. Maximum Power Dissipation vs Ambient Temperature for DDPAK/TO-263 Package  
HEATSINKING SO PowerPAD PACKAGE  
Heatsinking for the SO PowerPAD-8 package is accomplished by allowing heat to flow through the ground slug  
on the bottom of the package into the copper on the PC board. The heat slug must be soldered down to a  
copper plane to get good heat transfer. It can also be connected through vias to internal copper planes. Since  
the heat slug is at ground potential, traces must not be routed under it which are not at ground potential. Under  
all possible conditions, the junction temperature must be within the range specified under operating conditions.  
Figure 22 shows a curve for the θJA of the SO PowerPAD package for different copper area sizes using a typical  
PCB with one ounce copper in still air.

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest  
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale  
supplied at the time of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or  
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration  
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service  
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.  
TI is not responsible or liable for any such statements.  
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements  
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support  
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which  
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause  
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of  
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
