Choosing External Components
The input capacitor
C
I
is necessary for compensation of line influences. Using a resistor
of approx. 1 Ω in series with
C
I
, the oscillating circuit consisting of input inductivity and
input capacitance can be damped. The output capacitor is necessary for the stability of
the regulating circuit. Stability is guaranteed at values ≥ 22 µF and an ESR of ≤ 3 Ω
within the operating temperature range. For small tolerances of the reset delay the
spread of the capacitance of the delay capacitor and its temperature coefficient should
be noted.
