Precision voltage reference IC TL431 with T0-92 package is shown as the Figure 1. Its performance is continuously adjustable output voltage which is up to 36V, and the operating current range is 0.1. 100mA typical dynamic resistance is 0.22 Ω, and it has low output noise. Figure 2 is the typical application of the TL431, of which both ends of ③, ② feet output voltage V = 2.5 (R2 ten R3) V/R3. If you change the size of the resistance of R2, you can change the size of the output reference voltage. D5, D6, C2, C3 form the doubler circuit.
