The TPS709-Q1 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 TPS709-Q1 series is available in WSON-6 and SOT-23-5 packages.
The Texas Instruments TPS70933EVM-110 evaluation module (EVM) is a fully-assembled and tested circuit for evaluating the TPS79033 low-dropout regulator. This stand alone EVM has a low-dropout regulator IC for positive fixed-voltage regulation at 150-mA, input and output capacitors for stable (...)
