Notes:
(1) The ISR will operate at no load with reduced specifications.
(2) The Inhibit control (pin 1) has an internal pull-up and if it is left open circuit the module will operate when input power is applied. The open-circuit
voltage is the input voltage Vin. Use a discrete MOSFET to control the Inhibit pin, and ensure a transitioin time of less than ≤10s. Consult the related
application note for other interface considerations.
(3) For operation below 0°C, Cin and Cout must have stable characteristics. Use either low ESR tantalum or Oscon capacitors.
(4) See Safe Operating Area curves or contact the factory for the appropriate derating.
(5) The case pins on through-hole package types (suffixes N & A) must be soldered. For more information consult the applicable package outline drawing.
Input/Output Capacitors:
The PT6340 regulator series requires a 100F electrolytic (or tantalum) capacitor at the input and 330F at the output for proper
operation in all applications. In addition, the input capacitance, Cin, must be rated for a minimum of 740mArms of ripple current, and the ESR of the output
capacitor, Cout, must less than 50m @100kHz. For transient or dynamic load applications additional output capacitance may be necessary. For more information
consult the related application note on capacitor recommendations.
