TPS78342DDCT TI Low-Dropout Regulator | SOT-23-THIN | 3.3V Output, 150mA

Product Overview

The TPS78342DDCT from Texas Instruments is a low-dropout (LDO) linear regulator designed for power-sensitive applications. It offers a fixed output voltage of 3.3V with a maximum output current of 150mA. The device features a low dropout voltage of typically 200mV at full load, making it ideal for battery-powered systems. Its ultra-low quiescent current of 1µA (typical) extends battery life in portable electronics. The TPS78342DDCT is available in a compact SOT-23-THIN package, suitable for space-constrained designs.
