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
