SC4216 Very Low Input /Very Low Dropout 3 Amp Regulator With Enable POWER MANAGEMENT Features Description n Input Voltage as low as 1.45V The SC4216 is a high performance positive voltage regula- n 500mV dropout 3A tor designed for use in applications requiring very low n Adjustable output from 0.5V to 3.8V input voltage and very low dropout voltage at up to 3 n Over current and over temperature protection amperes. It operates with a Vin as low as 1.45V, with output n Enable pin voltage programmable as low as 0.5V. The SC4216 features n 10A quiescent current in shutdown ultra low dropout, ideal for applications where Vout is very n Full industrial temperature range close to Vin. Additionally, the SC4216 has an enable pin to n Available in SOIC-8-EDP Lead-free package, fully WEEE further reduce power dissipation while shut- down. The and RoHS compliant SC4216 provides excellent regulation over variations in line, load and temperature. Applications The SC4216 is available in the SOIC-8-EDP (Exposed Die Pad) package. The output voltage can be set via an exter- n Telecom/Networking cards nal divider or to xed settings of 0.5V and 1.2V depending n Motherboards/Peripheral cards on how the FB pin is con gured. n Industrial applications n Wireless infrastructure n Set top boxes n Medical equipment n Notebook computers n Battery powered systems Typical Application Circuit January 28, 2009 2009 Semtech Corporation 1SC4216 Pin Con guration Ordering Information Device Package (1)(2) SC4216STRT SOIC-8-EDP SC4216EVB Evaluation Board Notes: (1) Available in tape and reel only.
