3 Description

The TPS7A7002 is a high-performance, positivevoltage,

low-dropout (LDO) regulator designed for

use in applications requiring very-low input voltage

and very-low dropout voltage at up to 3 A. The device

operates with a single input voltage as low as

1.425 V, and with an output voltage programmable to

as low as 0.5 V. The output voltage can be set using

an external divider.

The TPS7A7002 features ultra-low dropout, ideal for

applications where VOUT is very close to VIN.

Additionally, the TPS7A7002 has an enable pin for

further reduced power dissipation while in Shutdown

mode. The TPS7A7002 provides excellent regulation

over variations in line, load, and temperature.

The TPS7A7002 is available in an 8-pin SO

PowerPAD™ package.
