    I have got a circuit which works as high current shunt regulator and indicator of battery status (for stethoscope). Input voltage from battery is 9V and output voltage 5V. I have finished my indicator yet, but I am not sure about regulator and his values. Can you help me with values of resistors in this regulator (R16, R20, R22)? I use diode TL431 in this circuit.
    Thank you very much
    Tom
