DUAL LINEAR CONTROLLER  
SC1538  
PRELIMINARY - August 24, 1999  
TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com  
DESCRIPTION  
FEATURES  
The SC1538 is a dual power supply controller designed  
to simplify power management on motherboards. It is  
part of Semtech’s Smart LDO™ family of products.  
The SC1538CS15/18 can provide a 1.818V power sup-  
ply for the I/O plane and a 1.515V power supply for the  
GTL+ and AGP planes. The SC1538CS25/25 can pro-  
vide two 2.525V supplies for clock and memory.

APPLICATIONS  
SC1538 features include Enable controls for each lin-  
ear FET controller and over current protection. Over  
current protection is provided by feedback to the sense  
pins. If any output drops below 1V (typical) for greater  
than 4ms (typical), that output will shut down.
