MIC5203

μCap

80mA Low-Dropout Regulator

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.

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

increases only slightly in dropout, further prolonging

battery life. Key MIC5203 features include current limiting,

overtemperature 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. Other voltages

are available.
