Application Circuit
The following Figure 3-1 shows one option of an application circuit. As explained above the resistor R_S can be left
out (see Figure 3-2). The resistor R_Q has to be in a dimension to match the applied V_S to keep I_Q limited to the
operating range of maximum 25 mA.
e.g.:
V_S = 12 V
I_Q = 12 V/1200 Ω = 10 mA
