6 Application information

Note: C

is required for stability. For value given, capacitor must be solid tantalum. If aluminium

electrolytic are used, at least ten times value should be selected. C

is required if regulator

is located an appreciable distance from power supply filter. 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.
