MIC2211-MFYML

MIC2211-MFYML Description

The MIC2211-MFYML is a dual linear low-dropout (LDO) voltage regulator designed for applications requiring high efficiency and low power consumption. Manufactured by Micrel Inc., this device is part of the Power Management Integrated Circuits (PMIC) category and is ideal for a wide range of electronic systems. The MIC2211-MFYML features a quiescent current of only 80 µA, ensuring minimal power loss during operation. It offers a fixed output configuration with two regulators, each providing a specific output voltage: 2.8V and 1.5V. The input voltage range extends up to 5.5V, making it suitable for various power supply sources.

The regulator is designed to handle output currents of 150mA and 300mA, with corresponding dropout voltages of 0.25V and 0.42V, respectively. This low dropout voltage ensures efficient operation even at low input-to-output voltage differentials. The MIC2211-MFYML also boasts a Power Supply Rejection Ratio (PSRR) that ranges from 60dB at 1kHz to 40dB at 20kHz, effectively filtering out noise from the input supply.
