Description

The SC4205 is a high performance positive voltage regulator designed for use in applications requiring very low dropout voltage at up to 1 Amp. Since it has superior dropout characteristics compared to regular LDOs, it can be used to supply 2.5V on motherboards or 2.8V on peripheral cards from the 3.3V supply thus allowing the elimination of costly heatsinks. Additionally, the SC4205 has an enable pin to further reduce power dissipation while shut down. The SC4205 provides excellent regulation over variations in line, load and temperature.
