REG113NA-2.85/3K TI LDO Regulator | SOT-23-5 | 2.85V Output, 400mA

Product Overview

The REG113NA-2.85/3K is a low-dropout (LDO) voltage regulator from Texas Instruments, offering a fixed output voltage of 2.85V with a maximum output current of 400mA. Housed in a compact SOT-23-5 package, this device is designed for space-constrained applications requiring high accuracy and low noise. With a dropout voltage of only 200mV at full load, it ensures efficient operation even with minimal input-to-output voltage differential. The REG113 series is known for its excellent line and load regulation, making it ideal for powering sensitive analog and digital circuits.
