Notes:
(1) All parameters, except nominal output voltage are specified for the variable voltage version, allowing a wider Vin Range.
The specified limits also apply for the fixed voltage versions.
(2) To maintain the specified junction temperatures, low duty cycle pulse testing is required for most parameters.
