TLV743105PDBVR TI LDO Regulator | SOT-23-5 | 1.05V Output, 300mA

Product Overview

The TLV743105PDBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 1.05V 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). With a typical dropout voltage of only 150mV at full load, it ensures efficient operation even with minimal input-to-output voltage differential. The TLV743105PDBVR features enable control, overcurrent protection, and thermal shutdown, making it a robust solution for powering sensitive analog and digital circuits.
