8.3 Do's and Don'ts

Do place at least one, low-ESR, 1-µF capacitor as close as possible between the OUT pin of the regulator and the GND pin.

Do place at least one, low-ESR, 0.1-µF capacitor as close as possible between the IN pin of the regulator and the GND pin.

Do provide adequate thermal paths away from the device.

Do not place the input or output capacitor more than 10 mm away from the regulator.

Do not exceed the absolute maximum ratings.

Do not float the Enable (EN) pin.

Do not resistively or inductively load the BYPASS pin.

Do not let the output voltage get more than 0.3 V above the input voltage.
