1 / 9 page  1 www.semtech.com SC4215A Very Low Input /Very Low Dropout 2 Amp Regulator With Enable POWER MANAGEMENT POWER MANAGEMENT Revision: April 25, 2007 The SC4215A 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 amperes. It operates with a Vin as low as 1.4V, with output voltage programmable as low as 0.5V. The SC4215A features ultra low dropout, ideal for applica- tions where Vout is very close to Vin. Additionally, the SC4215A has an enable pin to further reduce power dis- sipation while shut- down. The SC4215A provides ex- cellent regulation over variations in line, load and tem- perature. The SC4215A is available in the SOIC-8EDP (Exposed Die Pad) package. The output voltage can be set via an exter- nal divider or to fixed settings of 0.5V and 1.2V depend- ing on how the FB pin is configured. Input Voltage as low as 1.4V 400mV dropout @ 2A Adjustable output from 0.5V Over current and over temperature protection Enable pin 10µA quiescent current in shutdown Full industrial temperature range Available in SOIC-8EDP Lead-free package, fully WEEE and RoHS compliant Telecom/Networking cards Motherboards/Peripheral cards Industrial applications Wireless infrastructure Set top boxes Medical equipment Notebook computers Battery powered systems Description Features Applications Typical Application Circuits Volts R2 R2) (R1 0.5 VO + = ENABLE C1 R1 U1 SC4215A 1 2 3 5 4 8 7 6 NC EN VIN NC NC GND FB VO VO VIN R2 C2 C1 U1 SC4215A 1 2 3 5 4 8 7 6 NC EN VIN NC NC GND FB VO VO ENABLE VIN C2 V 5 . 0 VO = VIN C1 ENABLE U1 SC4215A 1 2 3 5 4 8 7 6 NC EN VIN NC NC GND FB VO VO C2 V 1 VO = 1.2V |
