REG102NA-A/3K TI LDO Regulator | SOT-23-5 | 250mA, 1.8V-5.5V

Product Overview

The REG102NA-A/3K from Texas Instruments is a high-performance, low-dropout (LDO) voltage regulator designed for space-constrained applications. Housed in a compact SOT-23-5 package, this device delivers up to 250mA of output current with a dropout voltage as low as 120mV at full load. It operates over an input voltage range of 1.8V to 5.5V, making it suitable for battery-powered and low-voltage systems. The REG102NA-A/3K features a fixed output voltage of 3.3V (A version) with ±2% accuracy over temperature, load, and line variations. Its low quiescent current (typically 25µA) and shutdown capability (less than 1µA) enhance power efficiency in portable electronics.
