LMS78_2.0R Series  
Wide Input Non-Isolated & Regulated, Single Output  
Switching Regulator  
Operating temperature:  
-40°C ~ +85°C  
Short circuit protection  
No-load input current as low  
as 0.1mA  
Efficiency up to 95%  
The LMS78_2.0R series are high efficiency switching regulators and ideal  
substitutes of LM78xx series three-terminal linear regulators. The  
product is featured with high efficiency, low loss and no heat sink requi-  
rement. They are widely used in industrial control, instrumentation,  
and electric power applications.
