Boost Converter Output Isn't Desired Value
For 5 volt in, 12 volt out the duty cycle is 1 - Vin/Vout or 58%. Since your output power is 200 ma @ 12 volts, (2.4 W) the average input current must be at least 480 mA. Since you are only on 58% ...

How to correctly indicate reponse time of a power supply
Well, no idea, you don't describe your system at all -- but there are a few typical cases, and one might argue anything else is pathological and would indicate bad design of the system, anyway.

How to correctly indicate reponse time of a power supply
Does the voltage drop happen exactly at the time that the current draw
is being increased?
Yes, but capacitance and inductance can make slight delays from the source to the load. In most power ...

Is the 7809 bad for a DC motor?
The 7809 itself is fine for a DC motor, but with caveats.
Input and output capacitors are needed for the 7809, but for your application, their absence would not make a difference significant enough to ...

Is the 7809 bad for a DC motor?
You left out the capacitors that the LM7809 datasheet specifies.
Three 18650 cells in series is anywhere from 7.5V (fully discharged) to 12.6V (fully charged.) The normal operating voltage is 3.7V ...

Is the 7809 bad for a DC motor?
Several issues here, some of which can be solved by reading the datasheet of the exact type of 7809 you're using.
The text of the datasheet will also say that those capacitors should be as close as ...

Help identify this SOT-23 5 pin component labeled ADU06 and weird behavior
From the image, we can see that it is connected to Pin 12 of the MCU. In the image from the datasheet we can see that this is a reset pin.
So this component is probably a voltage supervisor that has ...

Confusion in deciding a voltage regulator's input output capacitor types
The data sheet does not state what properties of the capacitor are important and in what range they should be.
Having said that, many older linear regulator data sheets recommend tantalum capacitors ...

Identify SMD voltage regulator with top marking: BDCM
The markings match with an ETA Solutions ETA6020S2G-T which is a load switch and not a regulator.
The markings with the underscore under the last character also points towards ETA Solutions. See the ...

Identify SMD voltage regulator with top marking: BDCM
I don't know about the exact part number, but the pinout should be easy to find:
I assume there isn't an inductor on the other side of the board...
The dot is the Pin 1 marker. I see some caps on this ...

How to Properly Select Resistors and Capacitors for a Voltage Reference Circuit with BJTs
To build a voltage reference that depends on BJTs without feedback, diodes and potentiometers is not a good idea. This will not offer good voltage stability.
You can select R6 and R7 based on the BJT ...
