 Sulzer regulators are well known and proved their efficiency over the years. Schematic offered here is slightly modified two-polarity Sulzer regulator which has some improvements over original one: 1. Active regulation elements (opamps U1 and U2) are supplied by capacitive multipliers Q1, R3, C5 and Q2, R4, C6 for negative rail respectively. 2. Reference voltage sources (Zener diodes D11 and D12 resp.) are fed by constant current sources (Q5, R13 and Q6, R15, R16 resp.) which ensures constant currents via D11, D12 and hence their constant working points. 3. Reference voltage sources are placed on the right (stabilized) sides of the regulators which ensures much more lower noise over them. 4. Diodes D9, D10 ensure normal start of the two rails no matter what load is connected. That schematic has very good capabilities (both simulated and measured) for ripple and noise suppression.
