FEATURES  
DESCRIPTION

•
Low IQ: 1µA  
The TPS782 family of low-dropout regulators (LDOs)  
offers the benefits of ultra-low power (IQ = 1µA), and  
miniaturized packaging (2×2 SON).

•
•
150mA, Low-Dropout Regulator  
Low-Dropout at +25°C, 130mV at 150mA  
Low-Dropout at +85°C, 175mV at 150mA  
3% 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  
(1µA), is ideal for microprocessors, memory cards,  
and smoke detectors.  
Available in Fixed Voltage Options (2.5V, 2.7V,  
and 2.8V) 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 1.0µF Ceramic Capacitor  
Thermal Shutdown and Overcurrent Protection  
CMOS Logic Level-Compatible Enable Pin  
Available in DDC (TSOT23-5) or DRV (2mm x  
2mm SON-6) Packages  
The TPS782 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 1.0µF. Therefore, this device requires  
minimal board space because of miniaturized  
packaging and a potentially small output capacitor.  
The TPS782 series also features thermal shutdown  
and current limit to protect the device during fault  
conditions. All packages have an operating  
temperature range of TJ = –40°C to +125°C. For  
APPLICATIONS

TI MSP430 Attach Applications  
Power Rails with Programming Mode  
Wireless Handsets, Smartphones, PDAs, MP3  
Players, and Other Battery-Operated Handheld  
Products  
high-performance applications that require  
a
dual-level voltage option, consider the TPS780  
series, with an IQ of 500nA and dynamic voltage  
scaling.
