Note

1:

The input capacitor is optional; Microchip recommends using a ceramic capacitor.

2:

These parts are tested at both 1 µF and 10 µF to ensure proper operation over this range of load capacitors. A wider

range of load capacitor values has been characterized successfully, but is not tested in production.
