General Description
The MIC5201 is an efficient linear voltage regulator
with very low dropout voltage (typically 17 mV at light
loads and 200 mV at 100 mA), and very low ground
current (1 mA at 100 mA output), offering better than
1% initial accuracy with a logic compatible on-off
switching input.
Designed especially for hand-held battery powered
devices, the MIC5201 can be switched by a CMOS or
TTL compatible enable signal. This enable control may
be connected directly to VIN if unneeded. When
disabled, power consumption drops nearly to zero. The
ground current of the MIC5201 increases only slightly
in dropout, further prolonging battery life. Key MIC5201
features include current limiting, overtemperature
shutdown, and protection against reversed battery.
The MIC5201 is available in several fixed voltages and
accuracy configurations. It features the same pinout as
the LT1121 with better performance. Other options are
available; contact Microchip for details.
