APPLICATION INFORMATION

Power-Supply Considerations

A 10µF bypass capacitor between IN and GND,

close to the device, is recommended. Placing a

high-value electrolytic capacitor on the output

pin(s) is recommended when the output load is

+5V

heavy. This precaution reduces power-supply

transients that may cause ringing on the input.

Optionally, bypassing the output with a 0.01µF to

0.1µF ceramic capacitor improves the immunity

of the device to short-circuit transients.
