LD29080DT33R ST LDO Regulator | DPAK | 3.3V Output, 800mA

Product Overview

The LD29080DT33R from STMicroelectronics is a low dropout (LDO) linear voltage regulator designed to deliver a fixed output voltage of 3.3V with an output current capability of up to 800mA. Housed in a DPAK (TO-252) surface-mount package, this device offers excellent regulation and low quiescent current, making it ideal for power-sensitive applications. The LD29080DT33R features a dropout voltage as low as 0.4V at full load, ensuring efficient operation even with minimal input-to-output voltage differential. It includes internal protection circuits such as current limit and thermal shutdown, enhancing system reliability.
