tive input voltage greater than 9V.  
These easy-to-use, 3-terminal, Inte-  
grated Switching Regulators (ISRs)  
have maximum output power of 10 to  
12 watts and a negative output voltage  
that is laser trimmed. They also have  
excellent line and load regulation.  
The PT78NR200 requires 100  
LFM of airflow at its maximum  
output current.  
The PT78NR200 series creates
