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

n Typical Application
