Hi,
Please give me the resistance values of R5, R6, R20, and VBG Voltage of Figure 33. I would like to calculate the calibration range of trim adjustment circuit which has some difference with figure 35.
REF01
Production
The REF01/REF02 are industry-standard precision voltage
references. The stable 10V output of the REF01
can be adjusted over a ±6% range with minimal effect...

Hi Jiro,
As stated in REF01 data-sheet "Newer designs should use ADR01". ADR01 offer high accuracy and temperature stability over wider operating range and maintains full pin to pin compatibility with the REF01. After analyzing the schematic R5 = 35k, R6~ 4.137k and R20= 20k. Please note for finer VOUT adjustment please add a series 470k resistor connecting trim pin. The core band gap voltage VBG = 1.057 V.
Please let me know if you have any additional questions.
Regards,
