Output voltage changes less than 0.1 V for load current change from 0 to 60 mA. Output voltage changes caused by change in load resistance affect gate-source voltage of FET Tr1 via R1 and R2, causing compensating change in drain cument. Additional transistors serve to reduce output resistance and increase output current without affecting stabilization ratio of about 1000.-C. R. Masson, F.EJf. Voltage Regulator, Wireless World, Aug.1971, p 386.
