* At Iout<Iout.min, the output may contain low frequency component that exceeds ripple specifications.
** Overcurrent protection is non-latching (hiccup type) 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
