| AIC1720 100mA Low Dropout Linear Regulator FEATURES Low Dropout Voltage of 130mV at 30mA Output Current (5V Output Version). Guaranteed 100mA Output Current. Internal P-MOSFET Draws no Base Current. Low Ground Current. Output Voltage of 3.0V/ 3.3V/ 3.6V/ 4.4V/ 5.0V Available. Input Voltage Range up to 14V. Needs only 1F for Stability. DESCRIPTION The AIC1720 is a 3-pin low dropout linear regulator. The superior characteristics of the AIC1720 include zero base current loss, low dropout voltage. Typical ground current remains approximately 55A, from no load to maximum loading conditions. Dropout voltage at 30mA output current is low: 130mV for the AIC1720-44 and AIC1720-50, 180mV for the AIC1720-30, AIC1720-33, and AIC1720-36. The AIC1720 comes in the popular 3-pin SOT-89, TO-92 and SO8 packages. APPLICATIONS Audio/Video System Wireless Communication Systems. Battery Powered Systems. Toys.
