n FEATURES
l l l l l l
n DESCRIPTION
The AIC1727 is a 3-pin low dropout linear regulator. The superior characteristics of the AIC1727 include zero base current loss, low dropout voltage and accurate output voltage. Typical ground current remains approximately 4 A, from no load to maximum loading conditions. The AIC1727 comes in the popular 3-pin SOT23, SOT-89, TO-92 packages.
4% Accuracy Output Voltage. Low Dropout Voltage Guaranteed 50mA Output Current. Internal P-MOSFET Draws no Base Current. Low Ground Current. Output Voltage of 3.0V/ 3.3V/ 3.6V/ 4.5V/ 5.0V Available. Input Voltage Range up to 13V. Needs only 1F for Stability.
