PMIC (Power Management Integrated Circuit) is an electronic integrated circuit that is responsible for controlling the power requirements within a device. Voltage regulators play an integral role in PMICs, providing a stable output voltage despite input voltage and current fluctuations. Over the years, linear voltage regulators have become an integral part of power management ICs, with models such as MC78L08ACPX providing a fixed 8V output. In this article, we will discuss the application field and working principle of the MC78L08ACPX linear voltage regulator.
Application Field
The MC78L08ACPX is a three terminal 8V Positive Voltage Regulator, suitable for a variety of applications that require a reliable and consistent 8V output voltage. It was specifically designed to be used in negative-ground systems, and can work with an input voltage of up to 40V. It is an ideal choice for handheld electronics and consumer applications due to its ability to efficiently convert a wide range of input voltage sources. It is also useful in automotive applications where it is used to regulate voltage provided by a battery. Other applications include small lighting systems and low-power dc-dc converters.
Working Principle
The MC78L08ACPX voltage regulator is a three terminal device, consisting of Input (Vin), Output (Vout) and Ground (Gnd) pins. The controller has two internal transistors, a reference voltage circuit, a series pass transistor and a voltage divider circuit. The output voltage is regulated by varying the reference current of the reference voltage circuit according to the differential voltage between the output pin and the voltage divider circuit.
When the input voltage (Vin) is greater than the fixed output voltage (Vout) of the regulator, the reference current increases to reduce the output voltage. Similarly, if the input voltage is lower than the predetermined output voltage, the reference current decreases. This will result in the regulated output voltage (Vout) being equal to the voltage set by the voltage divider circuit.
The device is also provided with on-chip current and thermal protection, making it suitable for applications that require a reliable power supply. The regulator also includes a short-circuit protection circuit, which ensures that the device will not be damaged if the output is short-circuited. The MC78L08ACPX is available in a TO-92 style package, allowing it to fit into small spaces and making it ideal for compact design.
Conclusion
The MC78L08ACPX linear voltage regulator is a reliable and cost-effective solution for various applications requiring a 8V output, and is particularly suitable for handheld electronics and consumer applications. Its compact size and easy-to-use three terminal design make it an ideal choice for those looking to integrate a linear voltage regulator into their design. With on-chip current and thermal protection, as well as short-circuit protection, the MC78L08ACPX is a dependable regulator capable of providing a consistent 8V output in a variety of power management situations.
