Additional Notes:
1. Vout can be increased up to 10% via the sense leads or up to 10% via the trim function, however total output voltage trim from all sources
should not exceed 10% of V OUT ( NOM ), in order to insure specified operation of over-voltage protection circuitry. See “Output Voltage Adjust/Trim” for
detailed information.
