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

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.
