REG102UA-A/2K5 TI LDO Regulator | 8-SOIC | 250mA, 1.8V-5.5V

Product Overview

The REG102UA-A/2K5 is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for applications requiring a stable and low-noise power supply. It delivers up to 250mA output current with a dropout voltage of typically 200mV at full load. The device operates over an input voltage range of 1.8V to 5.5V, making it suitable for battery-powered and low-voltage systems. The output voltage is fixed at 1.8V, 2.5V, 3.3V, or adjustable versions; the REG102UA-A/2K5 is the adjustable version with an output range of 1.2V to 5.5V set by external resistors. Housed in an 8-pin SOIC package, it offers excellent thermal performance and is specified over the industrial temperature range of -40°C to +125°C.
