GENERAL DESCRIPTION
The
AV
1084 is a positive and low dropout
three-terminal voltage regulator with 5A out-
put current capability. This device is design-
ed for use in low voltage applications that
offers lower dropout voltage and faster tran-
sient response.
This device is fully protected against over
current faults, over temperature operation,
reversed input polarity, reversed lead insert-
ion, transient voltage spike …etc.
On-Chips trimming the reference voltage to
1% and features the low dropout of maxi-
mum 1.45 volts.
The
AV
1084 Series regulators are available
in the popular industry standard TO-220,
TO-263 and TO-252 packages.
FEATURES
z
Very easy to use, it requires only two
external resistors to set the output voltage
z
Low dropout voltage:
1.2V typical at up to 5A
