General Description
The MIC5200 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 MIC5200 is switched by
a CMOS- or TTL-compatible logic signal. The ENABLE
control may be tied directly to V_IN if unneeded. 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 overtemperature shutdown.
The MIC5200 is available in several fixed voltages and
accuracy configurations. Other options are available;
contact Microchip for details.
