POWER MANAGEMENT Description
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 amps. It operates with a Vin as low as 1.6V, with output
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 variations in line, load and temperature. The SC4215 is available in the SOIC-8EDP package. The output
voltage can be set via an external or an internal resistive divider (2.5V) or to 0.8V depending on how the adjust pin is configured.
