Notes:
Note4: Simulated source impedance of 12μH. 12μH inductor in series with +Vin.
Note5: The RP12 series requires a minimum of 10% loading on the output to maintain specified
regulation. Operation under no-load condition will not damage these devices, however they
may not meet all listed specification.
Note6: The ON/OFF control pin voltage is referenced to -Vin pin.
