SC4215A  
Very Low Input /Very Low Dropout  
2 Amp Regulator With Enable  
POWER MANAGEMENT  
Description  
Features  
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  
amp. It operates with a Vin as low as 1.4V, with output  
voltage programmable as low as 0.5V. The SC4215A fea-  
tures ultra low dropout, ideal for applications where Vout  
is very close to Vin. Additionally, the SC4215A has an en-  
able pin to further reduce power dissipation while shut-  
down. The SC4215A provides excellent regulation over  
variations in line, load and temperature.  
‹ Input Voltage as low as 1.4V  
‹ 500mV dropout @ 2A  
‹ Adjustable output from 0.5V to 3.3V  
‹ Over current and over temperature protection  
‹ Enable pin  
‹ 10µA quiescent current in shutdown  
‹ Low reverse leakage (output to input)  
‹ Full industrial temperature range  
‹ Available in SOIC-8EDP package  
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 0.5V depending on how the FB pin is con-  
figured.  
Applications  
‹ Telecom/Networking cards  
‹ Motherboards/Peripheral cards  
‹ Industrial applications  
‹ Wireless infrastructure  
‹ Set top boxes  
‹ Medical equipment  
‹ Notebook computers  
‹ Battery powered systems
