The "721P" marking and claimed package matches with a RUNIC Tech RS721PXF Op Amp.

If you provide a picture of the surrounding components, I can check if the pin out and device type is plausible, otherwise you have to check for yourself.

    \$\begingroup\$ @GaneshThiva Your welcome. If this is the correct part, please accept the answer by clicking the check mark. I found it by simply google searching 'SOT-23-5 "721P" markings'. Sometimes it's that easy ;) (usually not though). \$\endgroup\$
