SC4213H
Very Low Input /Very Low Dropout
0.5 Amp Regulator With Enable
Description
The SC4213H is a high performance positive voltage regu-
lator designed for use in applications requiring very low
input voltage and very low dropout voltage at up to 0.5
amperes. It operates with a Vin as low as 1.4V. The SC4213H
features ultra low dropout, ideal for applications where
Vout is very close to Vin. Additionally, the SC4213H has an
enable pin to further reduce power dissipation while shut-
down. The SC4213H provides excellent regulation over
variations in line, load and temperature.
The SC4213H is available in an SOIC-8 package. The output
voltage can be set via an external divider as shown in the
typical application circuit.
