1A Low Dropout Positive  
Voltage Regulator  
AME1117  
nGeneral Descriptions  
nKey Features  
l Low dropout voltage ..............1.2V at 1A  
l Adjustable or fixed voltages 2.5V, 3.3V, 5.0V  
l Typical line regulation ....... 0.2%  
l Typical load regulation ...... 0.15%  
l Adjust pin current less than 90µA  
l Overcurrent protection  
The AME1117 is a 1A low-dropout positive voltage regu-  
lator. It is available in fixed and adjustable output  
voltage versions. Overcurrent and thermal protection  
are integrated onto the chip. Output current will limit  
as while it reaches the pre-set current or temperature  
limit. The dropout voltage is specified at 1.4V Maxi-  
mum at full rated output current. The AME1117 series  
provides excellent regulation over line, load and tem-  
perature variations.  
l Thermal protection  
l Available in TO-220, TO-252, SOT-223  
nApplications  
l High Efficiency Linear Regulators  
l 5V to 3.3V Voltage Converter  
l Battery Charger  
l Post Regulators for Switching Supplies
