Other Parts Discussed in Thread: LM4041-N
This shunt regulator is great for making a pull-down current source with an N-MOSFET.
Does TI or anyone else have a complementary part to make a pull-up current source with a P-MOSFET?
In other words, the reference on the ATL431 is relative to the anode, but what I need is a similar part with the reference relative to the cathode?
Does TI or anyone else make one, and If not, is there a simple circuit that would make an ultra low current ATL431-like compliment?
