SC4215 Very Low Input /Very Low Dropout 2 Amp Regulator With Enable POWER MANAGEMENT Features Description n Input Voltage as low as 1.6V The SC4215 is a high performance positive voltage regula- n 500mV dropout 2A tor designed for use in applications requiring very low n Adjustable output from 0.8V input voltage and very low dropout voltage at up to 2 n Over current and over temperature protection amperes. It operates with a Vin as low as 1.6V, with output n Enable pin voltage programmable as low as 0.8V. The SC4215 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 SC4215 has an enable pin to n Available in SOIC-8-EDP Pb-Free product. RoHS/WEEE further reduce power dissipation while shut down. The and Halogen Free compliant SC4215 provides excellent regulation over variations in line, load and temperature. Applications The SC4215 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 0.8V and 2.5V depending n Motherboards/Peripheral cards on how the ADJ pin is co gured. n Industrial applications n Wireless infrastructure n Set top boxes n Medical equipment n Notebook computers n Battery powered systems Typical Application Circuit October 8, 2009 1SC4215 Pin Con guration Ordering Information Device Package (1)(2) SC4215ISTRT SOIC-8-EDP SC4215IEVB Evaluation Board Notes: (1) Available in tape and reel only.
