Combines zener with opamp in bootstrap configuration. Regulated output current lO can be any value less than lz but must be much greaterthan opamp bias current. Current in zener is set by R1 to provide minimum of 1 mA. Performance can be improved by using Motorola MC1403 or other 2.5-V three-terminal voltage reference in place of zener. -W. Jung, AnIC Op Amp Update, Ham Radio, March 1978, p 62-69.
