TPS70933DBVR

TPS70933DBVR Description

The TPS70933DBVR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for precision power management in space-constrained applications. This fixed-output (3.3V) regulator delivers up to 150mA of output current with an ultra-low quiescent current of 2.05 µA, making it ideal for battery-powered and energy-efficient systems. Its wide input voltage range (up to 30V) and low dropout voltage (1.4V at 150mA) ensure stable operation even under varying supply conditions. Packaged in a compact SOT23-5 form factor, it is optimized for surface-mount designs requiring minimal board space.
