will this circuit work...?

[wikhtiar]

as its programing current is arround 0.1mA
it will wrok theratically but what about practically..........?

Yes, it will work but the current that flows through the bottom resistor varies with load, and thus will contribute some error. If your load doesn't vary too much, it will probably be ok. But you could use smaller resistors and avoid that problem.
