GENERAL DESCRIPTION
1
3A Fixed Low Dropout
Linear Regulator (LDO)
L1085-3.3
TO-252,263,220
JUL-05-2001
NIKO-SEM
The L1085 is a positive and low dropout
three-terminal voltage regulator with 3A 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 1.50 volts.
The L1085 Series regulators are available
in the popular industry standard TO-263
TO-220 and TO-252 packages.
