TPS709xx Series Voltage Regulators

TPS709xx Series Voltage Regulators

Texas Instruments' TPS709xx series of linear regulators are ultra-low 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.
