LDL40PURY ST LDO Regulator | 6-DFN(2x2) | 4A, 0.8V to 3.6V

Product Overview

The LDL40PURY from STMicroelectronics is a high-performance low-dropout (LDO) linear voltage regulator designed for applications requiring up to 4A output current. It operates from an input voltage range of 1.1V to 5.5V and provides an adjustable output voltage from 0.8V to 3.6V. Housed in a compact 6-DFN (2x2 mm) package, it offers excellent thermal performance and space-saving benefits. The device features ultra-low dropout voltage (typically 200mV at 4A), high PSRR (60dB at 1kHz), and low output noise (30µVrms), making it ideal for noise-sensitive power rails in communication, industrial, and automotive systems.
