Figure 29. Typical Application
power-supply considerations
A 0.01-
F to 0.1-F ceramic bypass capacitor between INx 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 heavy.
This precaution reduces power-supply transients that may cause ringing on the input. Additionally, bypassing
the output with a 0.01-
F to 0.1-F ceramic capacitor improves the immunity of the device to short-circuit
transients.
