In your application note, AN4835, you are using resistors R2 and R3. Please can you explain their purpose?My circuit uses the TSZ121 precision op-amp in the classical method without R2 and R3 and it works equally well. Thank you very much for any ins...

Thank you very much for your explanation. The Zener concept in HV supplies is an old one and well known.The important part to me was to understand, the use of additional resistors that reduce accuracy, yet have no obvious benefit. Again, thanks for y...
