Very Small Footprint  
These ISRs have a maximum output current  
of 1.5 Amps and an output voltage that is laser  
trimmed to a variety of industry standard volt-  
ages.  
These 78 series regulators have excel-  
lent line and load regulation with internal  
short- circuit and over-temperature protec-  
tion, and are offered in a variety of standard  
output voltages. These ISRs are very flex-  
ible and may be used in a wide variety of  
applications.
