REG102GA-2.8 TI LDO Regulator | SOT-223-6 | 2.8V Output, 250mA

Product Overview

The REG102GA-2.8 from Texas Instruments is a high-performance, low-dropout (LDO) voltage regulator designed to deliver a fixed 2.8V output with a maximum output current of 250mA. Housed in a compact SOT-223-6 package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. With a low dropout voltage of typically 200mV at full load, it ensures efficient operation even when the input voltage is close to the output. The REG102GA-2.8 also features a low quiescent current of 1mA, which helps extend battery life in portable devices. Its wide input voltage range from 2.5V to 10V provides flexibility for various power supply designs.
