ADJUSTABLE_REFERENCE
Two-transistor equivalent of zener is combined with Gulton 35TF1 thermistor to give voltage stability within 0.5% over 0-50℃ range, with output voltage adjustable from 3.5 to 15.5 V with R2. Dynamic impedance is only 1 ohm. Developed for regulator service in battery-powered MOS instruments.-R. Tenny, Compensated Adjustable Zener, EDN Magazine, May 5, 1973, p 72.
