** Overcurrent protection is non-latching with auto recovery.
*** 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 Vout (NOM) in order to ensure specified
operation of over-voltage protection circuitry.
