Description
The SC4217 is a 3A, high performance LDO designed for use in applications requiring very low input voltage and very low dropout voltage. It operates with an input voltage as low as 1.8V and a programmable output voltage from 1.24V. The SC4217 features ultra- low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the SC4217 has an enable pin to further reduce power dissipation while shut down. The SC4217 provides excellent regulation over line, load and temperature.
