Small current circuit breaker

Small current circuit breaker

“I had an Arduino Nano fail due to over-voltage when I used a breadboard power supply to power my breadboard. The breadboard power supply used an AMS1117 linear regulator to reduce the 12V from the plug pack I was using, to provide the 5V needed by the Arduino and some other modules. The AMS1117 failed (presumably due to overheating) and …

Adjustable Voltage Regulator

Adjustable Voltage Regulator

These circuits were made using two common adjustable voltage regulators - the LM317T and the AMS1117ADJ. The LM317T is an adjustable voltage linear regulator that is very popular. It was invented in 1970 and is still used today. This is very cheap component. Due to its characteristics, the way it reduces the output voltage is done at the expense of heat …

5V Voltage Regulator

5V Voltage Regulator

These circuits were made using four very common voltage regulators - the LM7805, the LM2940, the LM1117 and the AMS1117. The LM7805 is a linear voltage regulator that is very popular, because to put it to work no more components are needed. It is a very inexpensive component. Due to its characteristics, the way it reduces the output voltage is done …
