On Semi have released some low cost, constant current regulators that target LED drive, but have many more applications
Starting at $0.0545/10K, these are not the usual 'niche price nonsense' seen on other current regulator 2 terminal devices 'diodes'.
Right now in 20/25/30mA, hopefully they can do 5/10/15mA too, soon...

Look good, most likely calibrated JFETS (looking at the min. voltage they need). I would also be looking forward to 5/10 mA range which could be handy for some instrumentation purposes (not very likely to appear unless needed for huge displays, though :-) ).

I asked OnSemi, and they have 5mA and 10mA variants on the road map. With LED efficiency climbing, lower currents are a trend, and I could also see applications that use 5mA as a base current (Zero EMI), and then Dims using a higher current unit as well
Only feature they lack is a reverse-battery blocking ability...
