Device Overview

Summary

The MIC5203 is a µCap 80mA linear voltage regulator with very low dropout voltage (typically 20mV at light loads and 300mV at 80mA) and very low ground current (225µA at 20mA output), offering better than 3% initial accuracy with a logic-compatible enable input.

The µCap regulator design is optimized to work with low-value, low-cost ceramic capacitors. The outputs typically require only 0.47µF of output capacitance for stability.

Designed especially for handheld, battery-powered devices, the MIC5203 can be controlled by a CMOS- or TTL-compatible logic signal. When disabled, power consumption drops nearly to zero. If on-off control is not required, the enable pin may be tied to the input for 3-terminal operation. The ground current of the MIC5203 increases only slightly in dropout, further prolonging battery life. Key MIC5203 features include current limiting, over-temperature shutdown, and protection against reversed battery.

The MIC5203 is available in 2.8V, 3.0V, 3.3V, 3.6V, 3.8V, 4.0V, 4.5V, 4.75V, and 5.0V fixed voltages.
