Hi
I am working on a tracking system for vehicles (both cars and trucks).
The system power supply is the vehicle's battery (which supplies 12V or 24, for cars and trucks respectively), which may have many fluctuations (spikes, negative voltages, noise, transient voltages, etc.).
The tracking system needs 5V and 500mA constant (it may peak at 700mA), which means a regulator circuit from the vehicle battery (12-24V) to 5V (500mA~700mA) is necessary.
Price is an important factor, it should be as cheap as possible.
I have designed the following circuit to deal with the voltage regulation:
View attachment 64935
What do you think?
Do you have a different suggestion? I am open to different circuits (specially more simple ones), which regulate the voltage to 5V and protects from the voltage irregularities in the vehicle's battery.
Thanks in advance.
If you need to know anything else let me know.
