MIC2211-GOYML

MIC2211-GOYML Description

The MIC2211-GOYML is a dual linear voltage regulator designed by Micrel Inc., offering exceptional performance and reliability for a wide range of electronic applications. This device features a microcap LDO (Low Dropout) design, ensuring efficient power regulation even under low input-to-output voltage differentials. With a quiescent current of only 80 µA, the MIC2211-GOYML is optimized for low power consumption, making it ideal for battery-operated and energy-sensitive systems.

The regulator supports a maximum input voltage of 5.5V and provides two fixed output voltages: 1.8V and 2.9V. It can deliver output currents of up to 150mA and 300mA, respectively, with a dropout voltage of 0.25V at 150mA and 0.42V at 300mA. This low dropout voltage ensures that the regulator remains effective even when the input voltage is close to the output voltage, enhancing overall efficiency.

The MIC2211-GOYML also boasts a high power supply rejection ratio (PSRR) of 60dB to 40dB across the frequency range of 1kHz to 20kHz, which helps in maintaining stable output voltage under varying input conditions. The device is equipped with over-current and over-temperature protection features, ensuring robustness and reliability in operation.
