is a bias resistance for supplying the HA17431
cathode current and the output transistor Q base

This circuit supplies a constant current of

since the HA17431 cathode current is also
superimposed on I

.
The requirement in this circuit is that the cathode
current must be greater than Imin = 1 mA. The I
setting therefore must be on the order of several mA or
more.

In this circuit, the load is connected on the collector
side of transistor Q in circuit 7 above. In this case, the
load floats from GND, but the HA17431 cathode current
is not superimposed on I
, so that I
can be kept small
(1 mA or less is possible). The constant current value
is the same as for circuit 7 above:
