LDLN050PU33R ST Linear Voltage Regulator | 8-DFN(3x3) | 5.0V Input, 3.3V Output

Product Overview

The LDLN050PU33R from STMicroelectronics is a high-performance, low-dropout linear voltage regulator designed for applications requiring a stable 3.3V output from a 5.0V input. Housed in a compact 8-DFN (3x3 mm) package, it delivers up to 500 mA output current with excellent line and load regulation. Its low quiescent current and high PSRR make it ideal for noise-sensitive circuits in industrial, automotive, and consumer electronics.
