Bay Linear
Inspire the Linear Power
1.5A Positive Voltage Regulator
LM78XX
Description
The Bay Linear LM78XX is integrated linear positive
regulator with three terminals. The LM78XX offer several
fixed output voltages making them useful in wide range of
applications. When used as a zener diode/resistor combination
replacement, the LM78XX usually results in an effective
output impedance improvement of two orders of magnitude,
lower quiescent current.
The LM78XX is available in the TO-252, TO-220 & TO-263
packages,
