The SC4215 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

2 amperes. It operates with a Vin as low as 1.6V, with out-

put voltage programmable as low as 0.8V. The SC4215

features ultra low dropout, ideal for applications where Vout

is very close to Vin. Additionally, the SC4215 has an

enable pin to further reduce power dissipation while shut

down. The SC4215 provides excellent regulation over varia-

tions in line, load and temperature.

The SC4215 is available in the SOIC-8EDP (Exposed Die

Pad) package. The output voltage can be set via an

external divider or to fixed settings of 0.8V and 2.5V de-

pending on how the ADJ pin is configured.
