EXPLANATION
Fig 4. Typical Application of BL1084
The output voltage of adjustable version satisfies this followed equation:
Vout=VRef× (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 120Ω200Ω and the total output current of the adjustable
version of BL1084 needs to exceed 10mA to assure normal chip operation.
