General Description

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. TheµCap 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.
