AIC2951D General 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 condi-tions.
An error flag output, indicating when output volt-age drops out of regulation, often due to the falling batteries on the input, can be used for a power-on reset. A logic-controlled shutdown input enables the regulator to be switched on and off. The part may be configured for a fixed output voltage or programmed from 1.235V to 11V with an external pair of resistors. The part comes in 8-pin DIP or SO packages.
