LD49100PU18RY ST LDO Regulator | 6-DFN (3x3) | 1.8V Output, 1A Current

Product Overview

The LD49100PU18RY is a high-performance low-dropout (LDO) linear voltage regulator from STMicroelectronics, designed to deliver a fixed output voltage of 1.8V with a maximum output current of 1A. Housed in a compact 6-DFN (3x3 mm) package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. Its low dropout voltage (typically 200mV at 1A) ensures efficient operation even with small input-to-output voltage differentials.
