Manufacturer Part Number
l1084s3
Description
5a Adjustable Low Dropout Linear Regulator Ldo
Manufacturer
ETC-unknow
Datasheet
NIKO-SEM
GENERAL DESCRIPTION
The L1084 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 L1084 Series regulators are available
in the popular industry standard TO-220,
TO-263 and TO-252 packages.
