The OP
 

Can the 7805 and 1117-5 power supplies be used within ±0.05? [Copy link]

I have a sensor that requires 5V ±0.05V power supply. Does it meet the requirements of 7805 or AMS1117-5V?

The output voltage of 7805 is not necessarily exactly 5.00V, there is a relatively large deviation, and it is related to the output current.

This requirement requires the use of precision voltage stabilization, which cannot be achieved by conventional voltage stabilization power supplies. In addition, the ripple of a general switching power supply is already very good at 0.05V.

The TL431 manual says 1-100MA, but I only need 10MA, is that ok?  Details Published on 2020-9-12 11:00

I would like to ask, what is the current of the SOT23 package of TL431? I can't find the manual

There are many manufacturers of TL431. The manual can be found on TI's official website.

Just looking around
Find a datasheet?
