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 ≤10µs. 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 100µF electrolytic (or tantalum) capacitor at the input and 330µF 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 50mΩ @100kHz. For transient or dynamic load applications additional output capacitance may be necessary. For more information
consult the related application note on capacitor recommendations.
