7.3 Best Design Practices

Place input and output capacitors as close to the device as possible.

Use a ceramic output capacitor.

Do not exceed the device absolute maximum ratings.

7.4 Power Supply Recommendations

Connect a low output impedance power supply directly to the input pin of the device. Inductive impedances

between the input supply and the input pin can create significant voltage excursions at the input pin during

start-up or load transient events.
