Residual Load Voltage Characteristics
Note: When the current rating of the load is less than 10 mA, false operation may
occur. This is normal, and the problem can be cured by installing a bleeder resistor in
parallel with the load. Use the formulas given here to calculate the power rating and
value of the resistor.
