AME, Inc.
AME1084
n General Description
The AME1084 is a 5A 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 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 Features
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%

    ... AME, Inc. AME1084 n Application Description 1. Output Voltage Adjustment Like most regulators, the AME1084 regulates the out- put by comparing the output voltage to an internally gen- erated reference voltage. On the adjustable version, the V is available externally as 1.25V between V REF ADJ. The voltage ratio formed by R1 and R2 should be set to conduct 10mA (minimum output load) ...

    ... AME, Inc. AME1084 5. Thermal Consideration The AME1084 series contain thermal limiting circuitry designed to protect itself for over-temperature conditions. Even for normal load conditions, maximum junction tem- perature ratings must not be exceeded. As mention in thermal protection section, we need to consider all sources of thermal resistance between junction and am- bient ...
