SC4211
Very Low Input /Very Low Dropout
1 Amp Regulator With Enable
POWER MANAGEMENT
Description
The SC4211 is a high performance positive voltage
regulator designed for use in applications requiring very
low Input voltage and very low dropout voltage at up to
1 amperes. It operates with a Vin as low as 1.4V, with
output voltage programmable as low as 0.5V. The
SC4211 features ultra low dropout, ideal for applications
where Vout is very close to Vin. Additionally, the SC4211
has an enable pin to further reduce power dissipation
while shutdown. The SC4211 provides excellent regula-
tion over variations in line, load and temperature.
The SC4211 is available in the SOIC-8-EDP (Exposed Die
Pad) package. Depending on how the FB pin is config-
ured, the output voltage can be either externally adjusted
or fixed to either 0.5V or 1V.
