MIC5201
200mA Low-Dropout Regulator
General Description
The MIC5201 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 MIC5201 can be switched by a CMOS or TTL compatible
enable signal. This enable control may be connected directly
to V
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 Micrel for details.
