3 Description

The TPS709-Q1 series of linear regulators are ultralow,

quiescent current devices designed for powersensitive

applications. A precision band-gap and error

amplifier provides 2% accuracy over temperature.

Quiescent current of only 1μA makes these devices

designed 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.

These regulators can be put into shutdown mode by

pulling the EN pin low. The shutdown current in this

mode goes down to 150nA, typical.

The TPS709-Q1 series is available in WSON-6 and

SOT-23-5 packages.
