LD59100PUR ST LDO Regulator | 8-DFN(3x3) | 1A Output, 200mV Dropout

Product Overview

The LD59100PUR from STMicroelectronics is a high-performance low-dropout (LDO) linear voltage regulator designed for applications requiring a stable and low-noise power supply. With an output current capability of up to 1A and an ultra-low dropout voltage of only 200mV at full load, this device is ideal for powering sensitive analog and digital circuits. The LD59100PUR comes in a compact 8-DFN (3x3mm) package, making it suitable for space-constrained designs. It features a wide input voltage range from 2.5V to 5.5V and offers a fixed output voltage of 1.0V, with other output voltages available upon request. The regulator includes enable control, overcurrent protection, and thermal shutdown for robust operation.
