Integrated Switching Regulator  
SLTS061A  
(Revised 6/30/2000)  
High Efficiency > 85%  
Self-Contained Inductor  
Short Circuit Protection  
Over-Temperature Protection  
Regulators (ISRs). These ISRs have a  
maximum output current of -1.5 Amps  
and an output voltage that is laser  
trimmed to most industry standard volt-  
ages. They have excellent line and load  
regulation, and are ideal for applications,  
such as RS232 and Ethernet communica-  
tions, ECL logic, and op-amp circuitry.
