EXPLANATION
The output voltage of adjustable version satisfies this followed equation:
V_out= V_Refx(1+R2/R1)+IAdj×R2.
The second term IAdj×R2 can be ignored since the adjustable pin current IAdj (~ 50µA) is much
less than the current through R1 (~ 4mA).
The value of R1 is preferred in the range of 120Ω～200Ω and the total output current of the
adjustable version of LC1084 needs to exceed 10mA to assure normal chip operation.
