3 Description

The TPS7A7002 is a high-performance, positive- voltage, 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.
