TPS7250QD

TPS7250QD Description

The TPS7250QD from Texas Instruments is a fixed 5V, 250mA low-dropout (LDO) linear voltage regulator designed for precision power management in space-constrained applications. Housed in an 8-pin SOIC package, it features a 10V maximum input voltage and a low dropout voltage of 1.1V at 250mA, ensuring efficient operation even with small input-output differentials. The device boasts low quiescent current (225 µA) and low supply current (325 µA max), making it ideal for battery-powered systems. With 60dB PSRR at 120Hz, it delivers excellent noise rejection, critical for sensitive analog and digital circuits.
