LM78M00Series-Terminal Low Current
Positive Voltage Regulators
00000This series of fixed-voltage monolithic
integrated-circuit voltage regulators designed for a
wide range of applications. These applications include
on-card regulation for elimination of noise and
distribution problems associated with single-point
regulation. Each of these regulators can deliver up
to 500 mA of output current. The internal current
limiting and tamale shutdown features of these
regulators make them essentially immune to overload.

00A common ground is required between the input
and the output voltages. The input voltage must
remain typicaly 2.0V above the output voltage even
during the low point on the input ripple voltage.
*Cin is required if regulator is located in
0appreciable distance from power supply filter.
**CO is not needed for stability; however, it does
00improve transient response.
