Notes:
(1) ISR will operate down to no load with reduced specifications.
(2) The minimum input voltage required by the part is Vout +1.2V or 3.1V, whichever is greater.
(3) For operation below 0°C, use tantalum capacitors. For more information see the related applicatoin note, “PT6000/7000 Series Capacitor
Recommendations.”
(4) See Thermal Derating charts.
Input/Output Capacitors: The PT6500 series requires a 330µF electrolytic or tantalum input and output capacitor for proper operation in all applications. C1 (input)
must be rated for 1.2Arms and 100mΩ max. ESR. C2 (output) must must be rated for 400mArms ripple current and 0.2Ω max. ESR.
