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.
