MIC2211-VVYML-TR

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

The MIC2211-VVYML-TR is a dual fixed positive low dropout regulator from the MIC2211 series, manufactured by Microchip Technology. It provides two independent regulated outputs: Output 1 delivers up to 150mA at a fixed 3.6V, while Output 2 supplies up to 300mA at a fixed 3.6V. The device operates with an input voltage range of 2.25V to 5.5V and features extremely low ground current of 48µA total. It utilizes a 10-pin 3mm x 3mm MLF package.

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

What is the function of the CBYP pin?

The CBYP pin is used to bypass the internal reference voltage to ground with a capacitor to reduce output noise and increase power supply rejection.

How are the enable inputs configured?

The EN1 and EN2 pins are active-high logic inputs that allow individual control of each regulator's output state.
