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 poweris applied. The open-circuit

voltage is the input voltage V_in. 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 PT6440 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, C_in, must be rated for a minimum of 350mArms of ripple current, and the ESR of the output

capacitor, C_out, must less than 100mΩ @100kHz. For transient or dynamic load applications additional output capacitance may be necessary. For more information

consult the related application note on capacitor recommendations.
