The SC426H 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 3 amperes. It operates with a Vin as low as .45V, with output voltage programmable as low as 0.5V. The SC426H features ultra low dropout, ideal for applications where Vout is very close to Vin. Additionally, the SC426H has an enable pin to further reduce power dissipation while shutdown. The SC426H provides excellent regulation over variations in line, load and temperature. The SC426H 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.
