General Description
The MIC5202 is a family of dual linear voltage regulators with
very low dropout voltage (typically 17mV at light loads and
210mV at 100mA), and very low ground current (1mA at
100mA output–each section), offering better than 1% initial
accuracy with a logic compatible ON/OFF switching input.
Designed especially for hand-held battery powered devices,
the MIC5202 is switched by a CMOS or TTL compatible logic
signal. This ENABLE control my be tied directly to V
IN
if
unneeded. When disabled, power consumption drops nearly
to zero. The ground current of the MIC5202 increases only
slightly in dropout, further prolonging battery life. Key MIC5202
features include protection against reversed battery, current
limiting, and over-temperature shutdown.
The MIC5202 is available in several fixed voltages. Other
options are available; contact Micrel for details.
