TPS7A0321PDBVR TI LDO Regulator | SOT-23-5 | 500mA, 1μA Quiescent

Product Overview

The TPS7A0321PDBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for high-performance applications requiring low noise, low quiescent current, and small footprint. With an output current capability of 500 mA and a dropout voltage as low as 140 mV at full load, this device is ideal for powering sensitive analog and digital circuits. The fixed output voltage version (1.8V) ensures stable operation without external feedback resistors. The SOT-23-5 package enables compact PCB layouts.
