NJM78L08UA is one of the voltage regulators of the PMIC - Voltage Regulators family, which help to control and regulate the voltage applied to a given circuit. It is classified as a linear voltage regulator, and has many advantages over other forms of regulation, such as fast response time, low power consumption and high stability. This article provides an overview of the NJM78L08UA application field and its working principle.
Application Field of NJM78L08UA
NJM78L08UA is a 3-terminal regulator, which can be used for controlling the output voltage for a wide variety of applications. It is suitable for use in consumer electronics such as LCD TVs, digital cameras, multimedia players and other devices that require high voltage regulation. It is also suitable for industrial applications such as motor drivers, power supplies, and various other circuits with different loads.Working Principle of NJM78L08UA
The NJM78L08UA is a linear voltage regulator which employs a reference voltage to maintain the output voltage at a predetermined level. It works with an output voltage of 5V and a maximum output current of 100mA. The NJM78L08UA has an internal pass transistor, which is used to regulate the output voltage. This pass transistor is connected and controlled by an operational amplifier, which compares the output voltage to the reference voltage. If the output voltage is higher than the reference voltage, then the pass transistor is closed, and the output voltage becomes lower. Similarly, if the output voltage is lower than the reference voltage, then the pass transistor is opened, and the output voltage increases. In addition to the pass transistor, the NJM78L08UA also includes additional monitoring and protective functions such as over-voltage protection and over-temperature protection. The over-voltage protection prevents the output voltage from exceeding thereference voltage, and the over-temperature protection prevents the pass transistor from overheating due to excessive power dissipation.Advantages of using NJM78L08UA
NJM78L08UA provides several advantages over other forms of regulation such as switching, and it has been widely used in many types of applications. Some of the advantages of using NJM78L08UA are:- Fast response time due to its linear regulation.
- Low power consumption.
- High stability by maintaining the output voltage constant.
- Thermal protection for the pass transistor.
- Over-voltage protection.
