In this work, an exact solution of Einstein's field equations in isotropiccoordinates for anisotropic matter distribution is obtained by considering aparticular metric choice of metric potential $g_{rr}$. To check the feasibilityof the model, we have investigated all the physical characteristics of arealistic star. It is found that the model is potentially stable, and theadiabatic index is greater than $\frac{4}{3}$. The model have been analysed forCompact star \textbf{4U 1538-52}.
