DESCRIPTION
•2 Qualified for Automotive Applications
The TPS782xx family of low-dropout regulators
• Low I_Q: 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
• Available in Fixed Voltage Options (2.5 V,
2.7 V, 2.8 V, and 3 V) Using Innovative Factory
(LDOs) offers the benefits of ultra-low power
(I_Q = 1 μA), and miniaturized packaging (2-mm×2-mm
SON).
This LDO is designed specifically for battery-powered
applications where ultra-low quiescent current is a
critical parameter. The TPS782, with ultra-low I_Q
(1 μA), is ideal for microprocessors, memory cards,
and smoke detectors.

specific applications. Consult with your local factory
representative for exact voltage options and ordering
information; minimum order quantities may apply.
• 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 T_J = –40°C to 125°C. For
high-performance applications that require a
dual-level voltage option, consider the TPS780
series, with an I_Q of 500 nA and dynamic voltage
scaling.
