Good day,
I'm fabricating an undertaking I got as PCB+panel, sourcing my very own parts. It takes a clock supported through CD40106 and runs a CD4017. The consecutive yields of the CD4017 make a programmable arrangement of voltages that go to a LM358-based yield organize. The full schematic can be seen here. I simply acknowledged I didn't source the LM2931, which structures the +5V line for the computerized ICs. I checked the datasheet and resembles it's only a low-dropout 5V controller appraised at 100mA. Should great 78L05 voltage regulator fit the bill as a substitution for simply fueling 4XXX rationale? I'm practically certain it ought to be fine yet thought it's smarter to inquire. Here's the important piece of the schematic:
Likewise, I thought of utilizing a TL072 rather than the LM358 as I have a lot of these.
I have had a go at reaching the PCB maker with a past task additionally from him, however got no answer so I think I'll get everything dealt with speedier by simply asking here and making a few alterations all alone.
PS: The LM358 stage is only the typical 100k/100k adding blender for the CD4017 yields and afterward 100k/100k support with 15pF in the criticism way and 330R at the yield jack.
