To regulate the 12V supply down to 5V, we're using an LM2940CT5 linear voltage regulator, which is the automotiverated version of the ever popular LM7805 voltage.regulator. If you've used an LM7805 in another project, then an LM2940CT5 will seem perfectly familiar: it's in the same physical package, it has the same pinout, and you can drop it directly into a Heating coil Regulated output voltage Instrument voltage regulator Bimetal arm VoltageV supply input terminal Contacts Output side Radio Input side Figure 32.58 An instrument voltage regulator (IVR) is used to stabilize a fuel gauge.

The information passes through the computer and then to the gauge. Some earlier model vehicles have an instrument voltage regulator (IVR) to stabilize and limit voltage to the gauges. The use of an IVR provides more accurate gauge readings. When a vehicle has an IVR, it also has a radio (Figure 21–10) choke. A radio choke is a small coil At this occurrence, the voltage sensing circuit will record the sharp increase of voltage and a second range of values can be used. Depending of which side of the switch the voltage is sensed, it can represent two totally different temperatures (Figure 105).

No current will flow through diode D2 so long as the voltage stays below the operating voltage of the regulator. As soon as the alternator voltage reaches a preset value for which the regulator has been set to operate, the voltage across diode D2 achieves the breakdown value.When the alternator voltage is less than the battery (engine slow or not running for example), the direction of current flow is from the battery to the vehicle loads. The figure of 14.2 0.2V is the accepted charging voltage for a 12V system. to the star point, the energy can be collected. This can increase the power output.of an alternator by up to 15%.
