•
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

high-performance applications that require
a
dual-level voltage option, consider the TPS780
series, with an IQ of 500nA and dynamic voltage
scaling.
