LM78XX ( KA78XX, MC78XX) FI XED VOLTAGE REGULATOR ( POSI TI VE)  
3- TERMI NAL 1A POSI TI VE  
VOLTAGE REGULATORS  
TO- 220  
The LM78 XX series of three-terminal positive regul ators are avail abl e in  
the TO-220/D-PAK pack age and with several f ix ed output vol tages, mak ing  
them usef ul in a wide range of appl ications. Each ty pe empl oy s internal  
current l imiting, thermal shut-down and saf e area protection, mak ing it  
essential l y indestructibl e. I f adequate heat sink ing is provided, they can  
del iver over 1A output current. Al though designed primaril y as f ix ed vol tage  
D- PAK  
regul ators, these devices can be used with ex ternal components to obtain  
adj ustabl e vol tages and currents.
