The L7912CV is a linear voltage regulator specifically designed for applications that demand low noise, low power, and stability. It provides excellent linear accuracy in terms of output voltage accuracy and is particularly suitable for noise critical applications. This regulator is well suited for many applications such as battery-powered equipment, synchronous CPU power supplies, clock oscillators, LCDs, and other sensitive electronics.

The L7912CV is a low quiescent current regulator with a maximum output current of 1.5 Amps. Its design enables it to work as both a positive voltage regulator or as a negative voltage regulator. It is a three-terminal device consisting of an input pin, an output pin, and a ground pin. The L7912CV can provide a continuous output voltage of either 12 volts or -12 volts depending on the voltage applied to the input pin.

The most important feature of the L7912CV is its ability to maintain excellent output voltage accuracy. This linear regulator can guarantee a minimum output voltage accuracy of ±1.5 percent at room temperature, and it can guarantee an accuracy of ± 0.5 percent over the full temperature range. Additionally, the L7912CV has a very high power rating of up to 1.5 Amps and a very low temperature coefficient of 0.2%.

The main function of the L7912CV is to maintain a constant output voltage even when the supply voltage varies due to changes in temperature or line current. This is achieved by adjusting the output voltage with a control transistor, which provides the necessary current or voltage gain. The regulation is ensured by sensing the output voltage and comparing it to a reference voltage provided by a Zener diode. If the voltage output is lower than the reference voltage, the control transistor will turn on, resulting in an increase in current output, which in turn increases the output voltage. The opposite effect happens when the output voltage is higher than the reference voltage.

The L7912CV also features over-voltage and over-current protection, as well as thermal shutdown for added protection. This means that the regulator can be connected to a load that may draw more current than the rated current without any risk of damaging the device. At the same time, if the output voltage is too high, the device will shut itself down to prevent damage. Additionally, the L7912CV includes a built-in current limiter that can help protect downstream circuits from over-current faults.

Overall, the L7912CV is an excellent linear voltage regulator that offers multiple protection features, excellent accuracy and maximum current output. It is perfect for a wide variety of applications such as battery-powered equipment, synchronous CPU power supplies, clock oscillators, LCDs, and other sensitive electronics. The L7912CV is a reliable, reliable, and cost-effective solution that can help ensure that your sensitive electronic equipment runs safely and efficiently.
