Active Bias Controller
Characteristics
Supplies stable bias current even at low battery
voltage and extreme ambient temperature variation
Low voltage drop of 0.7V
Application notes
Stabilizing bias current of NPN transistors
and FET's from less than 0.2mA up to
more than 200mA
Ideal supplement for Sieget and other transistors
also usable as current source up to 5mA

mW it is not possible to exceed Ptot
respecting the maximum
300 ratings of VS and IContr.
The collector or drain
250 current (respectively) of
the stabilized RF transistor
200 does not affect BCR 400
directly, as it provides just the
150 base current.
