Notes:
(1) All parameters, except nominal output voltage are specified for the variable voltage version, allowing a wider V
in
Range.
The specified limits also apply for the fixed voltage versions over the allowable input voltage range: GS1085-1.8 (3.2V - 7.0V), GS1085-2.5 (3.9V - 7.0V),
GS1085-3.3 (4.75V - 7.0V).
(2) To maintain the specified junction temperatures, low duty cycle pulse testing is required for most parameters.
