TLV75519PDBVR TI LDO Regulator | SOT-23-5 | 1.9V Output, 500mA

Product Overview

The TLV75519PDBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments (TI), designed to deliver a fixed output voltage of 1.9V with a maximum output current of 500mA. Housed in a compact SOT-23-5 package, this device offers excellent line and load regulation, making it ideal for space-constrained and power-sensitive applications. With a low dropout voltage of typically 200mV at full load, the TLV75519PDBVR ensures efficient operation even when the input voltage is close to the output. The device also features thermal shutdown and current limit protection, enhancing system reliability.
