AME1086
1.5A Low Dropout
Positive Voltage Regulator
n General Description
The AME1086 is a 1.5A 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.).
AME1086 series regulators provide excellent regulation
over line, load and temperature variations.
