DESCRIPTION
The AIC1721/1721D is the enhanced CMOS
version
of
the
LP2950.
characteristics of the AIC1721/1721D include
zero base current loss, very low dropout voltage,
and 1% accuracy output voltage. Typica-l ground
current remains approximately 55
μ
A, from no
load to maximum loading conditions. Dropout
voltage at 100mA output current is significantly
lower than its bipolar counterpart: 130mV for the
AIC1721-5/1721D-5,
and
AIC1721/ 1721D. Output current limiting and
thermal limiting are built in to provide maximal
protection to the AIC1721/ 1721D against fault
conditions.
The
superior
180mV
for
the
While pin-to-pin compatible with the LP2950 and
the industry industry standard 78XX series of
voltage regulators, the AIC1721/1721D comes in
the popular3-pin SOT-89 or TO-92 packages.
