This is a switching regulator and they require the specified output capacitance which is 4.4uF given in the datasheet
we have given two 2.2uF capacitance at the regulator but one capacitance has 2 ohms resistor to it for intrinsic safety
will this still be considered as 4.4uF on total or will this cause any issues

Dear @vineeth_K ,
You can refer to our Application Note for SMPS Power supply requirements
Getting started with STM32U5 MCU hardware development - Application note - Figure 18.
Hope it helps you.
