The SC4216 is a high performance positive voltage regula-
tor designed for use in applications requiring very low
input voltage and very low dropout voltage at up to 3
amperes. It operates with a Vin as low as 1.45V, with output
voltage programmable as low as 0.5V. The SC4216 features
ultra low dropout, ideal for applications where Vout is very
close to Vin. Additionally, the SC4216 has an enable pin to
further reduce power dissipation while shut- down. The
SC4216 provides excellent regulation over variations in
line, load and temperature.
The SC4216 is available in the SOIC-8-EDP (Exposed Die
Pad) package. The output voltage can be set via an exter-
nal divider or to xed settings of 0.5V and 1.2V depending
on how the FB pin is con gured.
