MIC2211-GMBML-TR

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

The MIC2211-GMBML-TR is a dual-output fixed positive low dropout regulator manufactured by Microchip Technology. It provides two independent regulated outputs with voltages of 1.8V and 2.8V, sourced from a single input voltage range of 2.25V to 5.5V. The first regulator delivers up to 150mA, while the second supplies up to 300mA. Operating within a junction temperature range of -40°C to +125°C, it features an ultra-low quiescent current of 48µA total and high output accuracy of ±1.0%. The device utilizes a 10-pin 3mm × 3mm MLF™ leadless package.
