Power for LM199 temperature-stabilized voltage reference is obtained from output of LM108A buffer opamp, to permit use with to -25 V supply. 80K resistor is used in unregulated input to make circuit start properiy when power is applied.- Linear Applications, Vol. 2, National Semiconductor, Santa Clara, CA, 1976, AN-161, p 6.
