Application information
Fixed output regulator
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 electrolytic are used,
3. To improve transient response. If large capacitors are used, a high current diode from input to output
Split power supply (± 15 V - 1 A)
(*) Against potential latch-up problems.
at least ten times value should be selected. C1 is required if regulator is located an appreciable distance
from power supply filter.
(1N4001 or similar) should be introduced to protect the device from momentary input short circuit.
