Typical Applications
Figure 6. Negative Fixed output regulator
Figure 7. Split power supply (
±
12V/1A)
Note:
(1) To specify an output voltage, substitute voltage value for "XX "
(2) Required for stability. For value given, capacitor must be solid tantalum. If aluminium electronics are used, at least ten times
value shown should be selected. C
I
is required if regulator is located an appreciable distance from power supply filter.
(3) To improve transient response. If large capacitors are used, a high current diode from input to output (1N400l or similar)
should be introduced to protect the device from momentary input short circuit.
