Introduction

NJM2870F21-TE1 is a high-efficiency, high-reliability voltage regulator from NJRC. This voltage regulator is a linear regulator that is designed to provide 24V at 2A load current and features very low dropout voltage and low power dissipation. In addition, this device has excellent line and load regulation characteristics and is capable of supplying high output current and providing stable output voltage. This voltage regulator is very small in size and can operate at a temperature range of -20°C to +70°C.

Application Field

NJM2870F21-TE1 voltage regulator is most suitable for use in power management systems, especially where high output current is required. It can be used in industrial fractional-horsepower (FHP) motors, low dropout regulator (LDO) applications, as well as battery charging systems. This voltage regulator can also be used in applications such as voltage regulation for motor control and digital ICs, as well as other heavy-duty, high-current applications.

Working Principle

The NJM2870F21-TE1 voltage regulator uses linear regulating technology. This technology works by using an input voltage, regulating it to the desired output voltage using an internal voltage reference. This reference voltage is compared to both the input and output voltages. When the output voltage reaches the reference voltage, the voltage regulator will stop regulating the voltage and the output voltage will stay at the voltage reference. The voltage regulator also features a very low dropout voltage, meaning that it can operate even when the input voltage is near the output voltage.

The NJM2870F21-TE1 has a push-pull output stage to drive the output externally. This output stage allows the device to regulate an output voltage with low noise, precise regulation and minimal power dissipation. The voltage regulator is also equipped with a thermal shut-down feature which will shut down the device if the temperature becomes too high.

In addition to its thermal shut-down service, the NJM2870F21-TE1 also has short-circuit protection and current limit protection. These features ensure the safety of the system in case of a short-circuit or over-current situation. The device also features over-voltage protection and under-voltage protection, which will protect both the voltage regulator and the system.

Conclusion

The NJM2870F21-TE1 is a high-efficiency, high-reliability voltage regulator with excellent line and load regulation characteristics. It features very low dropout voltage and low power dissipation, enabling it to provide high output current and stable output voltage. This device can operate at a temperature range of -20°C to +70°C, making it suitable for use in a wide range of power management applications. In addition, the device has various protection features such as thermal shut-down, short-circuit protection, current limit protection, over-voltage protection, and under-voltage protection, making it a reliable and safe solution.
