>Is there a good way of making a T-Flip-Flop too?
no good one. you'd need an edge detector, which means capacitors, which gets fiddly. or you'd need a whole master-slave DFF
>Also that's an interesting looking dual-mode linear power supply
it's just a conceptual sketch. I hadn't even had coffee yet when I drew it
>My designs always require rail-to-rail op-amps
otoh my sketch requires a floating input supply because of the load-current-dependent offset introduced by the sense resistor
easier high-side current measurement: use a lower-voltage RRIO op amp (LMV321 or similar are nearly jellybean by now) as a voltage-to-current converter measuring some milliohm sense resistor with respect to V+. power it with picrel, Vdd tied to V+, but Vss tied to a zener and emitter follower
