Introduction

The NJM78L24L2A is a compact and powerful Low Drop Out (LDO) linear voltage regulator ideal for low current applications. It provides excellent noise performance, making it suitable for use in RF and analog circuits. As a member of the NJM78LXX family, the NJM78L24L2A can supply a maximum output current of 350mA, making it suitable for a variety of medium-to-high current applications. The NJM78L24L2A is a dual output device, allowing two outputs to be regulated simultaneously.

Application Field

The NJM78L24L2A has high current and low noise performance, making it an ideal choice for a wide range of applications, such as power supplies for consumer electronics, batteries, and automotive systems. It can also be used in telecommunications, instrumentation, industrial, and medical systems. The NJM78L24L2A is especially suited for use in low noise analog circuits, such as radio frequency (RF) systems. Additionally, its wide input voltage range and low drop-out characteristics make it an ideal solution for use in automotive, battery-powered and industrial applications.

Working Principle

The NJM78L24L2A features a three-terminal voltage regulator circuit which is designed to provide a regulated output voltage with very low noise. It is a linear regulator, meaning that it works by passing a fixed amount of the current to ground to maintain the output voltage at a predetermined level. The NJM78L24L2A has a very low voltage drop-out, meaning that the regulator will still maintain its output voltage despite very low input voltage differences. This is important for powering systems that require an unusually low input voltage, such as automotive systems. Additionally, the NJM78L24L2A features an internal thermal protection circuit, allowing it to shut down in the case of an over-temperature condition.

Features and Benefits

The NJM78L24L2A provides a variety of advantages over other voltage regulators, such as:• Low drop-out performance: The NJM78L24L2A has a very low minimum input voltage difference, allowing it to be used in applications where the input voltage is close to the output voltage.• High output current: The NJM78L24L2A can provide up to 350mA of output current, making it suitable for medium-to-high current applications.• High-power supply rejection ratio: The NJM78L24L2A has a high-power supply rejection ratio, meaning that it is able to reject noise from the power source, making it suitable for use in noise-sensitive circuits.• Thermal protection: The NJM78L24L2A has an internal thermal protection circuit, preventing the regulator from overheating and shutting down in the event of an over-temperature condition.• Dual-output: The NJM78L24L2A can provide two regulated outputs, allowing two devices to be powered simultaneously.

Conclusion

The NJM78L24L2A is a versatile, high-performance linear voltage regulator, providing excellent performance in a small form factor. Its low drop-out performance and high power reject ratio make it suitable for a wide range of applications, including RF, telecommunications, and automotive systems. Additionally, its dual-output capability, thermal protection, and high output current make it an ideal solution for powering multiple devices.
