3 Description
The TPS709xx 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.
These regulators can be put into shutdown mode by
pulling the EN pin low. The shutdown current in this
mode goes down to 150 nA, typical.
The TPS709xx series is available in WSON-6 and
SOT-23-5 packages.
