AME1084
5A Low Dropout Positive Voltage Regulator
n General Description
The AME1084 is a 5A low-dropout positive voltage regulator. 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.
