MIC5200
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 espe-
cially 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
When disabled, 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 protection against reversed battery, current limiting,
and over-temperature shutdown.
The MIC5200 is available in several fixed voltages and ac-
curacy configurations. Other options are available; contact
Micrel for details.
