Well it's U23 so look in the parts list.  Maybe it's a voltage regulator.

I recently found a burned resistor in a voltmeter.  I replaced it and solved that problem, but analysis shows that the resistor had to be defective because there was no mechanism for it to overheat.  It had changed from 100 Ohms to several thousand Ohms and was in a constant current circuit.

Is it NJM78L10A? 10V LDO regulator
