AIC1740

AIC1740 Low Output Voltage, 500mA Low Dropout Linear Regulator n FEATURES l l l n DESCRIPTION The AIC1740 is a 3-pin low dropout linear regulator. The superior characteristics of the AIC1740 include zero base current loss, very low dropout voltage, and 2% accuracy output voltage. Typical ground current remains approximately 65 µA, from no load to maximum loading conditions. Dropout voltage is exceptionally low. Output current limiting and thermal limiting are built in to provide maximal protection to the AIC1740 against fault conditions. The AIC1740 comes in the popular SOT-223, TO-251 and TO-252 packages. l l l l l Low Dropout Voltage of 900mV at 500mA Output Current (3.0V Output Version). Guaranteed 500mA Output Current.
