Ñ1, Ñ2 – smoothing capacitors, C1=10 mkF, Ñ2=100 mkF (Ta),
D1 - IC,
R1, R2 - resistors, R1=121 Îì ± 1%, R2 – adjusted with accuracy 1%.
Output voltage Uo, V, is defined by formula:
UO
= U ref (1 +

I Adj R 2
,
Where Uref - reference voltage, V,
I Adj - adjustment current, mkA.
Since IADJ has values not more than 120 mkA, inaccuracy dependent on this
value for Uo – is minor.
