Solution:

enter image description here

From the values of op voltage and output current it is clear that this is a low voltage Low current Regulator [LVLC]

To calculate $R_1$ and $R_2$ :-

Assume that current through $R_1$ and $R_2$ to be equal to $1 \mathrm{~mA}$

$ \begin{aligned} \therefore R_2 &=\frac{V}{I}=\frac{5 \mathrm{~V}}{1 \mathrm{~mA}}=5 \mathrm{k} …
