Notes:

(1) The PT6210 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.
(2) The ISR will operate to no load with reduced specifications.
(3) Input voltage cannot exceed 30V when the inhibit function is used.
(4) See Thermal Derating charts.
(5) Consult the related application note for guidance on adjusting the output voltage.
