SC4216H Very Low Input /Very Low Dropout 3 Amp Regulator With Enable POWER MANAGEMENT Features Description Input Voltage as low as 1.45V The SC4216H is a high performance positive voltage regu- 500mV dropout 3A lator designed for use in applications requiring very low Adjustable output from 0.5V input voltage and very low dropout voltage at up to 3 Over current and over temperature protection amperes. It operates with a Vin as low as 1.45V, with output Enable pin voltage programmable as low as 0.5V. The SC4216H fea- 10A quiescent current in shutdown tures ultra low dropout, ideal for applications where Vout Full industrial temperature range is very close to Vin. Additionally, the SC4216H has an Available in SOIC-8-EDP Lead-free package, fully WEEE enable pin to further reduce power dissipation while shut- and RoHS compliant and halogen-free down. The SC4216H provides excellent regulation over variations in line, load and temperature. Applications The SC4216H is available in the SOIC-8-EDP (Exposed Die Pad) package. The output voltage can be set via an exter- Telecom/Networking cards nal divider or to a fixed setting of 0.5V depending on how Motherboards/Peripheral cards the FB pin is configured.
