Practical Example
Consider the example of a photocoupler, with an internal light emitting diode V
F
= 1.05 V and I
F
= 2.5 mA,
power supply output voltage V
2
= 5 V, and bias resistance R
2
current of approximately 1/5 I
F
at 0.5 mA. If
the shunt regulator V
K
= 3 V, the following values are found.
R

= 316(
) (330

= 2.1(k
) (2.2k
from E24 series)
Next, assume that R
3
= R
4
= 10 k
. This gives a 5 V output. If R
5
= 3.3 k
and C
1
= 0.022

F, the
following values are found.
