    Let’s analyze the slow-start principle of this circuit:
    Assume that the parasitic capacitance between the gate and the source of the MOS transistor Q1 is Cgs, the parasitic capacitance between the gate and the drain is Cgd, the parasitic capacitance between the drain and the source is Cds, and the gate-drain is connected in parallel with the capacitor C2 (C2gt; >Cgd), so the total gate-drain capacitance C’gd=C2+ Cgd, since the capacitance of Cgd is almost negligible relative to C2, so C’gd≈C2, the turn-on voltage of the MOS transistor gate is Vth, during normal operation, the gate-source voltage of the MOS tube is Vw (this voltage is equal to the clamping voltage of the voltage regulator tube D3), the charging time constant of the capacitor C1 is t=(R1//R2//R3)C1, because R3 is usually more R1 and R2 are much larger, so t≈(R1//R2)C1.
