onesansinv 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 55µA, 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.
