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 120Ω～200Ω and the total output current of the adjustable

version of BL1084 needs to exceed 10mA to assure normal chip operation.
