Reference amplifier, consisting of integrated zener diode and npn transistor, acts with Q2 to maintain constant reference voltage across R4. Current through R4 equals load current except for relatively small base currents of Q2 and Q3. Current drift over l5 hours is less than 0.01%.- Trclnsislor Manual, Seventh Edition, General Electric Co.1964, p 233.
