TLV73318PDBVR TI LDO Regulator | SOT-23-5 | 1.8V Output, 300mA

Product Overview

The TLV73318PDBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 1.8V 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 quiescent current and high PSRR. With an ultra-low dropout voltage of typically 130mV at 300mA load, it ensures efficient operation even when the input voltage is close to the output. The TLV73318PDBVR is ideal for powering sensitive analog and digital circuits in battery-powered devices, industrial sensors, and communication systems.
