It is also possible to use an open drain output device, such as the TLV182x, but the output pull-up resistor must also be taken into account in the calculations. The pull-up resistor is seen in series with the feedback resistor when the output is high. Thus, the feedback resistor is actually seen as R2 + RPULLUP. TI recommends that the pull-up resistor be at least 10 times less than the feedback resistor value.
