LDL40PU50RY ST LDO Regulator | 6-DFN (2x2) | 4.0V, 500mA, Low Dropout

Product Overview

The LDL40PU50RY from STMicroelectronics is a high-performance low-dropout (LDO) linear voltage regulator designed for applications requiring a stable and precise 4.0V output. Housed in a compact 6-DFN (2x2 mm) package, it delivers up to 500 mA output current with a typical dropout voltage of only 200 mV at full load. The device features low quiescent current, high PSRR, and excellent transient response, making it ideal for noise-sensitive power rails in industrial, automotive, and consumer electronics.
