Frequently asked questions
A negative voltage Low-dropout (LDO) regulator is a type of LM7912 regulator whose input and output voltages are both negative. The input voltage is regulated from high to low in absolute value.
The LM337 is an adjustable three-terminal negative-voltage regulator capable of supplying in excess of –1.5A over an output voltage range of –1.2V to –37 V. They require only 2 external resistors to set the output voltage and one output capacitor for the frequency compensation system.
A negative voltage simply means that there is a potential difference between two points in an electric circuit diagram. This potential difference can be caused by either a direct current (DC) or an alternating current (AC) source system.
-12v is 12 volts below ground. We don't use voltage below ground much in digital electronics Projects (indeed, exposing any Arduino pin to a voltage below ground will damage it), but it's quite common with analog signal stuff.
To put it simply, it's a reference to GND. If you connect a wire to the ground and current flows TO the ground, then it's the positive side. If current instead flows FROM the ground, then it would be a negative regulator Transistor I believe.
