Another pin you can use on the Nano to power it up is the 5V pin (located on Pin 27, close to the VIN pin at the end of the board). This pin mostly serves as a power output pin that supplies power ...

These three pin metal cans were very common, especially the LM340 5V regulator which was, of course, a linear regulator. Today, you are more likely to see a 7805 in a TO-220 case or something ...

A 5V -> 1.5V low power LDO (Low Drop-Out) is a type of voltage regulator designed to provide a stable output voltage of 1.5 volts from a 5-volt input ...

This IP is a Low-Dropout (LDO) 5V to 3.3V&1.5V power regulator in GSMC 0.13um low power 4P5M e-flash dual gate process. The max output currents are 60mA (for 3.3V output) and 40mA (for 1.5V output), ...

Throwing a 5V regulator like the LM7805 at our projects can become habit forming, after all they’re dirt cheap and the circuit is about as basic as they come with only two external components… ...
