Can a 5V regulator connect directly to a voltage divider to obtain a 2V output?

In my circuit, a lm78l05 is used to provide +5V voltage to other parts. And now I need another +2V source to shift my input signal from +-2V to 0~4V as the ADC ad7682 limits the input signal range from 0~4V.

Can I just connect the lm78l05 with a simple voltage divider(maybe made by ada4841)?(as the picture showed)

If yes, any parameters I should consider carefully such as the opamp offset current/voltage or input resistance of opamp?

If no, any good suggestion to achieve the goal?

Thank you very much!
