Automotive 150-mA, 30-V, ultra-low-IQ, low-dropout voltage regulator with reverse current protection

The TPS709-Q1 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 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.
