General Description
The AME1084 is a 5A low-dropout positive voltage regu-
lator. It is available in fixed and adjustable output volt-
age 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.
