Features, Applications

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 up to more than 200mA Ideal supplement for Sieget and other transistors also usable as current source to 5mA

Maximum Ratings Parameter Source voltage Control current Control voltage Reverse voltage between all terminals Total power dissipation, 83 C Junction temperature Storage temperature Symbol VS IContr. VContr. VR Ptot Tj Tstg Value Unit mW C

Thermal Resistance Junction ambient 1) Thermal resistance, chip case RthJA RthJC 280 190 K/W

Electrical Characteristics at TA=25C, unless otherwise specified Symbol Values Parameter min. DC Characteristics Additional current consumption 3 V Lowest stabilizing current 3 V Imin 20 40 typ. max.

DC Characteristics with stabilized NPN-Transistors Lowest sufficient battery voltage IB (NPN) 0.5 mA Voltage drop (VS - VCE) 25 mA Change of IC versus hFE = 50 Change of IC versus 3 V Change of IC versus TA Vdrop IC /IC IC /IC IC /IC hFE / hFE VS /VS

Collector current = f (hFE ) IC and hFE refer to stabilized NPN Transistor Parameter Rext.
Collector Current = f (VS) of stabilized NPN Transistor Parameter Rext.
