10 Board Options
Refer to the bill of materials in section 11.2 for recommended values and sources for the following optional com-
ponents.
10.1. Schottky Diode
While D1 is not required, it can be populated to increase efficiency and provide a better load regulation. Care
should be taken to select a diode that is rated to handle the output current supplied by the regulator.
10.2. Zener Diode
Zener diodes, D2 and D3, are not populated. However, adding D2 or D3 is highly recommended to protect the
ZSPM4521 by clamping the input voltage to the maximum input voltage of 7.2V.
