Qualified for Automotive Applications  
The TPS782xx family of low-dropout regulators  
(LDOs) offers the benefits of ultra-low power  
(IQ = 1 μA), and miniaturized packaging (2-mm×2-mm  
SON).  
Low IQ: 1 μA  
150-mA Low-Dropout Regulator  
Low Dropout at 25°C: 130 mV at 150 mA  
Low Dropout at 85°C: 175 mV at 150 mA  
4% Accuracy Over Load/Line/Temperature  
This LDO is designed specifically for battery-powered  
applications where ultra-low quiescent current is a  
critical parameter. The TPS782, with ultra-low IQ  
(1 μA), is ideal for microprocessors, memory cards,  
and smoke detectors.  
Available in Fixed Voltage Options (2.5 V,  
2.7 V, 2.8 V, and 3 V) Using Innovative Factory  
EEPROM Programming  
The ultra-low power and miniaturized packaging allow  
designers to customize power consumption for  
specific applications. Consult with your local factory  
representative for exact voltage options and ordering  
information; minimum order quantities may apply.

Stable with a 1-μF Ceramic Capacitor  
Thermal Shutdown and Overcurrent Protection  
CMOS Logic Level Compatible Enable Pin  
Available in DDC (TSOT23-5) or DRV (2-mm x  
2-mm SON-6) Packages  
The TPS782xx family is designed to be compatible  
with the TI MSP430 and other similar products. The  
enable pin (EN) is compatible with standard CMOS  
logic. This LDO is stable with any output capacitor  
greater than 1.0 μF. Therefore, this device requires  
minimal board space because of miniaturized  
packaging and a potentially small output capacitor.  
The TPS782xx series also features thermal shutdown  
and current limit to protect the device during fault  
conditions. The devices have an operating  
temperature range of TJ = –40°C to 125°C. For
