TLV77128PDBVR TI LDO Regulator | SOT-23-5 | 1.8V Output, 300mA

Product Overview

The TLV77128PDBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a fixed 1.8V output with a maximum output current of 300mA. Housed in a compact SOT-23-5 package, this device offers excellent line and load regulation, making it ideal for space-constrained applications requiring a stable and low-noise power supply. With a dropout voltage as low as 200mV at full load, it efficiently regulates from input voltages as low as 2.0V up to 5.5V.
