n Features
AME1084
n General Description
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 it reaches the
pre-set current or temperature limit. At full rated output
current the dropout voltage is 1.4V (max.). AME1084
series regulators provide excellent regulation over line,
load and temperature variations.
n Applications
Rev.N.03
The AME1084 is a 5A low-dropout positive voltage regu-
l Low Dropout Voltage ----- 1.4V at 5A
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 90 A
l Overcurrent Protection
l Thermal Protection
l Available in TO-220, TO-263, TO-252
l All AME’ s Lead Free Products Meet RoHS
l High Efficiency Linear Regulators
l Post Regulators for Switching Supplies
l 5V to 3.3V Voltage Converter
l Battery Charger
