1.5 AMP POSITIVE STEP-DOWN  
INTEGRATED SWITCHING REGULATOR  
Revised 6/30/98  
Very Small Footprint  
The 78ST100 is a series of wide input  
High Efficiency > 85%  
Self-Contained Inductor  
Internal Short-Circuit Protection  
Over-Temperature Protection  
Fast Transient Response  
Wide Input Range  
voltage, 3-terminal Integrated Switching  
Regulators (ISRs). These ISRs have a maxi-  
mum output current of 1.5A and an output  
voltage that is laser trimmed to a variety of  
industry standard voltages.  
These 78 series regulators have excellent  
line and load regulation with internal short-  
circuit and over-temperature protection, are  
very flexible, and may be used in a wide  
variety of applications.
