MIC5200

100mA Low-Dropout Voltage Regulator

Preliminary Information

General Description

The MIC5200 is an efficient linear voltage regulator with very

low dropout voltage (typically 17mV at light loads and 200mV

at 100mA), and very low ground current (1mA at 100mA

output), offering better than 1% initial accuracy with a logic

compatible ON/OFF switching input. Designed especially for

hand-held battery powered devices, the MIC5200 is switched

by a CMOS or TTL compatible logic signal. The ENABLE

control may be tied directly to V

power consumption drops nearly to zero. The ground current

of the MIC5200 increases only slightly in dropout, further

prolonging battery life. Key MIC5200 features include protec-

tion against reversed battery, current limiting, and over-

temperature shutdown.

The MIC5200 is available in several fixed voltages and

accuracy configurations. Other options are available; contact

Micrel for details.
