com IC of adjustable voltage regulator of positive polarity with low residual voltage and load current 3 А TO-220 IC IL1084 is a powerful adjustable voltage regulator of positive polarity with low residual voltage and load current 3,2 А.
IC of powerful adjustable voltage regulator with low residual voltage lower than 1,5A and reference voltage 1,25 V is purposed for producing constant temperature-stabilized voltage of positive polarity by means of the value set by external resistive divider and used in electronic equipment as a source of stabilized supply.

Output voltage Uo, V, is defined by formula:: U O = U ref (1 + R2 ) + I Adj R 2 , R1 Where U ref - 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.
