Notes:
1. The diode D1 is used to protect the module against a reverse connection.
2. C1 is required if a high voltage input to the regulator is used. It will help prevent voltage spikes that could possibly damage
the regulator. If used, the value should be 47 µF maximum.
3. In the application circuit, a second, regulated, output is provided by adding another regulator. For information on other circuits
(filtering, protection, etc.) please contact the factory.
