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.

FEATURES
