TLV74311PDBVR TI LDO Regulator | SOT-23-5 | 1.1V Fixed Output, 300mA

Product Overview

The TLV74311PDBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, offering a fixed output voltage of 1.1V 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 130mV at 300mA load, it ensures efficient regulation even under low input-to-output voltage differentials. The TLV74311PDBVR features enable control, overcurrent protection, and thermal shutdown, making it a reliable choice for powering sensitive analog and digital circuits.
