Notes: (1) ISR-will operate down to no load with reduced specifications.
(2) Total output voltage variation includes load regulation droop, which is required for compliance with specification VRM 8.4-5
(3) The Standby input (pin 6) has an internal pull-up. If it is left open-circuit the module will operate when input power is applied. A low-leakage
MOSFET is recommended to control this input. The open-circuit voltage is nominally 5V. See application notes for interface considerations.
(4) For operation below 0°C, Cout must have stable characteristics. Use either low ESR tantalum or Oscon capacitors.
(5) See safe Operating Area curves or consult factory for the appropriate derating.
(6) The PT8100 regulators require a minimum of 660F, low ESR ouput capacitance (1,200F for standard aluminum electrolytic) for proper operation.
(7) The case pins on the through-hole package types (suffixes N & A) must be soldered. For more information see the applicable package outline drawing.
Input Filter: The filter components L1 and C3 are optional for most applications. The inductor must be rated to handle the projected input current. A rating of 20ADC is
recommended. The input capacitance, C1 must be rated for a minimum of 1Arms of ripple current. For transient or dynamic load applications, additional capacitance
may be required. For more information refer to the application note on capacitor recommendations for this product.
