GENERAL DESCRIPTION  
FEATURES  
The AV1084 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.  
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-220, TO-263 and TO-252 packages  
On-Chips trimming the reference voltage to  
1% and features the low dropout of maxi-  
mum 1.45 volts.  
The AV1084 Series regulators are available  
in the popular industry standard TO-220,  
TO-263 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
