LD49100PU15RY ST LDO Regulator | 6-DFN(3x3) | 1A, 1.5V Fixed Output

Product Overview

The LD49100PU15RY is a high-performance, low-dropout (LDO) linear voltage regulator from STMicroelectronics, designed to deliver up to 1A of output current with a fixed output voltage of 1.5V. Housed in a compact 6-DFN (3x3mm) package, it offers excellent line and load regulation, making it ideal for noise-sensitive applications. The device features a low dropout voltage of typically 200mV at full load, enabling efficient operation even with small input-to-output voltage differentials. Its wide input voltage range from 2.5V to 6V allows flexibility in various power supply designs.
