General Description
The MIC5202 is a dual linear voltage regulator with low
dropout voltage (typically 17 mV at light loads and
210 mV at 100 mA), and low ground current (1 mA at
100 mA per output). Ideal for battery-operated
applications, the MIC5202 offers 1% output voltage
accuracy and dual enable pins. The enable pins may
be driven individually or tied directly to V_IN. When the
part is disabled, power consumption drops to nearly
zero. The MIC5202 ground current increases slightly in
dropout, which minimizes power consumption and
increases battery life. Some key features include
reversed battery protection, current-limit, and
overtemperature protection.
The MIC5202 is available in fixed output voltages in the
small 8-pin SOIC package.
