Description
The SC427 is a 3A, high performance LDO designed for
use in applications requiring very low input voltage and
very low dropout voltage. It operates with an input volt-
age as low as .8V and a programmable output voltage
from .24V. The SC427 features ultra- low dropout, ideal
for applications where V
is very close to V
. Addi-
tionally, the SC427 has an enable pin to further reduce
power dissipation while shut down. The SC427 provides
excellent regulation over line, load and temperature.
The SC427 is available in a TO263-5 package and is fully
WEEE and RoHS compliant.
