The SC425H 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 .4V, with output voltage programmable as low as 0.5V. The SC425H features ultra low dropout, ideal for applications where Vout is very close to Vin. Additionally, the SC425H has an enable pin to further reduce power dissipation while shutdown. The SC425H provides excellent regulation over variations in line, load and temperature. The SC425H is available in the SOIC-8-EDP (Exposed Die Pad) package. The output voltage can be set via an external divider or to a fixed setting of 0.5V depending on how the FB pin is configured.
