The AME1505 is a 5A low-dropout positive voltage regu-
lator. The dropout voltage of AME1505 is 750mV at maxi-
mum output current. The output voltage is preset at fac-
tory. It is available in fixed and adjustable output voltage
versions. The fixed voltage range could expand from 1.25V
to 3.7V, where 5V and 3.3V voltage supplies are avail-
able. AME1505 has 2 new features: First, a remote Sense
pin is wired out to eliminate output voltage variation due
to load changes. Secondly, an extra Control pin is avail-
able to effectively decrease Vin to Vo drop. It greatly
improves the power dissipation.
Overcurrent and thermal protection are integrated onto
the chip. Output current will limit as it reaches the pre-
set current. AME1505 series have excellent regulation
over line, load and temperature variations.
