TPS7A20185PDBVR TI LDO Regulator | SOT-23-5 | 1.85V Output, 300mA

Product Overview

The TPS7A20185PDBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 1.85V with a maximum output current of 300mA. Housed in a compact SOT-23-5 package, this device is designed for space-constrained applications requiring low noise and high power-supply rejection ratio (PSRR). Its ultra-low dropout voltage (typically 140mV at full load) ensures efficient operation even with small input-to-output voltage differentials. The TPS7A20185PDBVR is ideal for powering sensitive analog and digital circuits in industrial, automotive, and communication systems.
