Any MOSFET similar of ULN2003?
zapta:
The ULN2003 has multiple channels (I need only 4), can be driven directly from 5V MCU and has protection diodes for inductive load (e.g. 28BYJ-48 stepper motor) but has high saturation voltage because of the darlington driver. Is there a similar MOSFET IC, with closer to zero saturation voltage?
Psi:
what current do you need to switch?
Maybe this?

Search digikey in the "PMIC - Power Distribution Switches" section.
There are lots of multichannel driver ICs that have built in fets and accept logic level input.
Many are intended to drive inductive loads and dont need a back emf diode

Maybe the TI TPIC family of power arrays
Ie. (Or see companion prods in bottom)

100ma per channel at 2 out of the 4 channel, plus some margin. This is to operate this stepper motor http://robocraft.ru/files/datasheet/28BYJ-48.pdf on 5V USB power.

Yes, this is what I looked for. Will give it a try. Thanks.
