LM78XX (KA78XX, MC78XX) FIXED VOLTAGE REGULATOR (POSITIVE)
Fig. 8 Fixed Output Regulator Fig. 9 Constant Current Regulator
Notes
:
(1) To specify an output voltage. substitute voltage value for "XX."
A common ground is required between the input and the Output
voltage. The input voltage must remain typically 2.0V above the output
voltage even during the low point on the input ripple voltage.
(2) C
is required if regulator is located an appreciable distance from
power Supply filter.
(3) C
O
improves stability and transient response.
