Description

General part information

TPS783 Series

The TPS783 family of low-dropout regulators (LDOs) offers the benefits of ultralow power and miniaturized packaging.

This LDO family is designed specifically for battery-powered applications where ultralow quiescent current is a critical parameter. The TPS783, with ultralow IQ(500 nA), is ideal for microprocessors, microcontrollers, and other battery-powered applications.

The absence of pulldown circuitry at the output of the LDO provides the flexibility to use the regulator output capacitor as a temporary backup power supply (for example, during battery replacement).
