can i use more than a 7805 in a circuit?
2y
Yes, you can use more than one 7805 voltage regulator in a single circuit.
There are a couple of scenarios where this might be useful:
-
Separating Power Loads: If your circuit has multiple sections that each require a well-regulated 5V supply, but each section might introduce noise into the voltage supply, then you might use one 7805 for each section. This way, the noise produced by any one section will not affect the others.
-
Increasing Power Capability: If your circuit's total power demand exceeds the power output capability of a single 7805, you might use multiple 7805 regulators in parallel, each feeding a part of your circuit. However, it's essential to evenly distribute the power load to each regulator since they may not share the load equally due to their slight differences in characteristics. A better approach when needing more current is to use a power regulator with a higher current rating.
Remember that each 7805 will need its own input and output capacitors as per its datasheet, often a 10uF capacitor at the input and a 0.1uF at the output are used.
Please note that your current schematic shows two 7805 voltage regulators (designators: 7805 SENSORI, 7805 MICRO) in your circuit, so you are indeed using more than one 7805 in your current design.

how can i add a hole into the pcb?
2y
In Flux, you can add a hole in your PCB layout by following these steps:
-
Navigate to the PCB layout editor from the Schematic editor if you're not already there.
-
Select the appropriate layer for the hole. If you want a through-hole which spans all layers, you can select any layer.
-
On the right-hand side toolbox, click on the 'Hole' tool.
-
Click on the PCB layout where you would like to place the hole. A hole should appear at your pointer's location.
-
You can adjust the size of the hole by selecting it and changing its diameter property in the property inspector window.
Remember, the hole you just added is non-conductive. If you wish to add a drill hole that is plated (i.e., it has conductive lining that allows it to connect signals from different layers), you would instead use the 'Via' tool and just not connect it to any traces.
These steps are based on typical EDA (Electronic Design Automation) software workflow, as of my knowledge cut-off in September 2023. Make sure to check for any specific updates or changes in the current version of Flux you are using.

can i use more than a 7805 in a circuit?
2y
Yes, you can use more than one 7805 voltage regulator in a circuit, as long as each 7805 regulator is properly connected and is not overloaded in terms of maximum current output. Frequently, multiple 7805 regulators are used when you need to powers different parts of a circuit separately, or when you need to spread out the power dissipation across multiple components to avoid overheating a single component.
Keep in mind the following guidelines when using multiple 7805 voltage regulators:
- Each 7805 regulator requires a certain voltage input (Vin) to function correctly. For the 7805, this will typically be 7.5V or greater. Ensure each regulator is provided with its necessary Vin.
- Don't exceed the maximum current output of each regulator. For a 7805, this is generally around 1 Amp, but depending on the specific model, it could be more or less.
- Provide sufficient heat sinking if necessary, as linear regulators such as the 7805 can dissipate significant heat use. More regulators spreading the load means less heat per component, but you'll still need to manage the overall thermal characteristics of your circuit.
- Note that each 7805 will have its own Vin and Ground, while providing a regulated +5V output. These power supplies should not be mixed, to avoid potential shorts or irregular behavior.
Finally, depending on the complexity of your project and the power demands of your various components, there could be more efficient solutions than using multiple 7805 voltage regulators. For instance, you might consider a switching regulator or a power management IC in scenarios where you're dealing with high current draws or you need to maintain high power efficiency.
