Figure 1 :
Fixed Output Regulator.
Figure 2 :
Split PowerSupply (
±
15V/1A).
Notes :
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 electrolitics are used, at least ten times
value should be selected. C
1
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 (1N4001 or similar) should
be introduced to protect the device from momentary input short
circuit.
Against potential latch-up problems.
