MAX8860EUA30+T

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MAX8860EUA30+T is a low-noise, low-dropout linear regulator from Analog Devices/Maxim Integrated. It operates with an input voltage range of 2.5V to 6.5V and delivers up to 300mA output current. The device provides a fixed 3.0V output in preset mode or can be configured for adjustable outputs between 1.25V and 6.5V using the Dual Mode feature. Typical supply current is 120µA, with shutdown current at 10nA. Dropout voltage is typically 105mV at 200mA load. Output noise is 60µVRMS. It includes thermal overload, short-circuit, and reverse battery protection within an 8-pin µMAX package.
