5A Fixed Low Dropout
Linear Regulator (LDO)
L1084-3.3
TO-252,263,220
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-263
TO-220 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
z Low ground current
z Fast transient response
z Current & thermal limiting
z Line regulation: 0.5% typical
z Load regulation: 0.5% typical
z TO-263, TO-220 and TO-252 packages
APPLICATIONS
z High current microprocessor supplies
z Low voltage logic supply
z Powering VGA & sound card
z Portable instrumentation
z Constant current regulator
z Post regulator for switching power supply
