Overview
MIC5202 Micrel MIC5202 Dual 100mA Low-Dropout Voltage Regulator Preliminary Information 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 VIN 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.
