TPS78318DDCR TI Low-Dropout Regulator | SOT-23-THIN | 1.8V Output, 150mA

Product Overview

The TPS78318DDCR from Texas Instruments is a high-performance, low-dropout (LDO) voltage regulator designed for power-sensitive applications. It delivers a fixed output voltage of 1.8V with a maximum output current of 150mA. The device features ultra-low quiescent current (typically 0.5µA) and low dropout voltage (typically 120mV at 150mA), making it ideal for battery-powered and portable electronics. Housed in a compact SOT-23-THIN package, the TPS78318DDCR offers excellent thermal performance and space-saving benefits.
