DESCRIPTION

The AIC2951/ 2951D series is the enhanced CMOS version of the LP2951. The superior char acteristics of the AIC2951/ 2951D series include zero base current loss, very low dropout voltage, and 1 accuracy output voltage. Typical ground current remains approximately 55mA, from no load to maximum loading conditions. Dropout voltage at 100mA output current is significantly lower than its bipolar counterpart: 130mV for the AIC2951-50/2951D-50, 180mV for the AIC2951-

33/ 2951D-33, and 200mV for the AIC2951-30/2951D-30. Output current limiting and thermal limiting are built in to provide maximal protection to the AIC2951/2951D series from fault conditions.
