REG101NA-2.85/3K TI LDO Regulator | SOT-23-5 | 2.85V Output, 100mA

Product Overview

The REG101NA-2.85/3K is a low-dropout (LDO) linear voltage regulator from Texas Instruments (TI), designed to deliver a fixed output voltage of 2.85V with a maximum output current of 100mA. Housed in a compact SOT-23-5 package, this device offers excellent line and load regulation, making it ideal for space-constrained applications requiring a stable and low-noise power supply. The REG101 series is known for its low dropout voltage (typically 120mV at 100mA) and low quiescent current (typically 1µA in shutdown mode), which enhances battery life in portable devices.
