It operates with VIN as low as 1.6V and up to 6V, making it useful for a wide range of different applications and rails. The output voltage is programmable down to 0.5V, set via an external resistor divider, or to a fixed setting of 0.5V depending upon how the FB pin is configured. The SC4212B has an enable pin to further reduce power dissipation while shut down. Protection features include over current protection, over temperature protection and reverse blocking from output to input. The SC4212B is available in a 3mm x 3mm MLPD-8 package.
