TPS78319DDCT TI Low-Dropout Regulator | SOT-23-THIN | 1.9V Output, 150mA

Product Overview

The TPS78319DDCT from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for power-sensitive applications. It delivers a fixed output voltage of 1.9V with a maximum output current of 150mA. Housed in a compact SOT-23-THIN package, this device offers excellent line and load regulation, making it ideal for noise-sensitive circuits. The TPS78319DDCT features a low dropout voltage of typically 120mV at full load, enabling efficient operation even when the input voltage is close to the output. Its low quiescent current of 1µA (typical) extends battery life in portable devices. The device also includes overcurrent and thermal shutdown protection for robust performance.
