3A Low Dropout  
Positive Voltage Regulator  
AME1085  
n General Description  
n Key Features  
l Low dropout voltage 1.2V typically at 3A  
l Adjustable or 3.3V fixed voltage  
l Line regulation typically 0.015%  
l Load regulation typically 0.05%  
l Adjust pin (ADJ) current less than 90υA  
l Overcurrent protection  
The AME1085 is a 3A low-dropout positive voltage regu-  
lator. It is available in fixed and adjustable output voltage  
versions. Overcurrent and thermal protection are inte-  
grated onto the chip. Output current will limit as it reaches  
the pre-set current or temperature limit. At full rated  
output current the dropout voltage is 1.4V (max.).  
AME1085 series regulators provide excellent regulation  
over line, load and temperature variations.  
l Thermal protection  
l Available in TO-220, TO-263, TO-252  
n Applications  
l High Efficiency Linear Regulators  
l Post Regulators for Switching Supplies  
l 5V to 3.3V Voltage Converter  
l Battery Charger
