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.
APPLICATIONS
The AIC1720 comes in the popular 3-pin
Audio/Video System
Wireless Communication Systems.
Battery Powered Systems.
Toys.
SOT-89, TO-92 and SO8 packages.

Guaranteed by design.
Regulation is measured at constant junction temperature, using pulse testing with a low ON time.
Dropout voltage is defined as the input to output differential at which the output voltage drops
100mV below the value measured with a 1V differential.
