*1.
Resistor R should be 75 k
Ω or less to prevent oscillation.
*2.
Diode Di instantaneously discharges the charge stored in the capacitor (C) at the
power falling,Di can be removed when the delay of the falling time is not important.

Remark
When the power rises sharply as shown in the Figure 31 left, the output may goes to the high level
for an instant in the undefined region where the output voltage is undefined since the power
voltage is less than the minimum operation voltage.
