LDO40LPURY ST LDO Regulator | 6-DFN(3x3) | 400mA, 38V

Product Overview

The LDO40LPURY is a high-voltage, low-dropout linear voltage regulator from STMicroelectronics, designed for automotive and industrial applications. It delivers up to 400 mA output current with a wide input voltage range from 4 V to 38 V. The device features a very low dropout voltage (typically 200 mV at 400 mA) and excellent line/load regulation, making it ideal for powering sensitive analog and digital circuits. Housed in a compact 6-DFN (3x3 mm) package, it offers high power density and thermal performance.
