REG102GA-5

REG102GA-5 Description

The REG102GA-5 from Texas Instruments is a fixed 5V, 250mA low-dropout (LDO) linear voltage regulator designed for precision power management in space-constrained applications. Housed in a compact SOT-223-6 package, this regulator delivers stable output with a minimal dropout voltage of 0.27V at 250mA, making it ideal for battery-powered and portable devices. With an input voltage range up to 10V, it ensures reliable performance in diverse power supply scenarios. The device features low quiescent current (500 µA) and high PSRR (65dB at 120Hz), reducing noise and improving efficiency in sensitive analog and digital circuits.
