3 Description

The TPS709 series of linear regulators are ultralow,

quiescent current devices designed for power-

sensitive applications. A precision band-gap and error

amplifier provides 2% accuracy over temperature.

Quiescent current of only 1 µA makes these

devices ideal solutions for battery-powered, always-

on systems that require very little idle-state power

dissipation. These devices have thermal-shutdown,

current-limit, and reverse-current protections for

added safety.

Shutdown mode is enabled by pulling the EN pin low.

The shutdown current in this mode goes down to

150 nA, typical.

The TPS709 series is available in WSON-6 and

SOT-23-5 packages.
