MIC5202
Dual, 100mA Low-Dropout Regulator
General Description
The MIC5202 is a dual linear voltage regulator with low
dropout voltage (typically 17mV at light loads and 210mV
at 100mA), and low ground current (1mA at 100mA 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.
