TPS77518DR TI LDO Regulator | 8-SOIC | 1.8V Output, 500mA

Product Overview

The TPS77518DR from Texas Instruments is a low-dropout (LDO) voltage regulator designed to deliver a fixed 1.8V output with a maximum current of 500mA. Housed in an 8-pin SOIC package, this device offers excellent line and load regulation, making it suitable for a wide range of applications requiring a stable and low-noise power supply. The TPS77518DR features a low dropout voltage of typically 169mV at full load, enabling efficient operation even when the input voltage is close to the output. It also includes an enable pin for power sequencing and a built-in overcurrent and thermal protection.
