The load and line regulation of this circuit is better than 0.001%.Noise, drift, and long-term stability are determined by Zener D1. Noise can be reduced by inserting 100-kΩ resistors in series with both inputs of the LM108A, and bypassing the noninverting input to ground. A 100-pF capacitor between the LM108A output and the inverting input prevents frequency stability. Temperature drift can be reduced by adjusting R4 for minimum drift. For best results, remote sensing should be made directly to the load terminals, as shown.
