MIC5203
μ Cap 80mA Low-Dropout Regulator
General Description
Features
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.
Designed especially for hand-held, 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
