The NJM79L18A Voltage Regulator is a voltage regulation device with linear output and wide versatility. The device is designed for use in systems for applications where a regulated output voltage and/or current is required.

This device usually has a lower cost than a switched mode regulator and is thus ideal for applications that require long-term stability and reliability. It is designed with a monolithic integrated circuit, making it compact and efficient.

The NJM79L18A provides two distinct functions, which are an adjustable voltage regulator, and a reference voltage source. The adjustable voltage regulator can be adjusted to output any desired voltage within the specified output range. The reference voltage source provides a stable output, and can be used to set fixed voltage limits.

The NJM79L18A has a typical output current of 500mA, with a maximum output current of 1A. The adjustable regulating voltage range is typically 0.8V to 44V in ±2% increments, providing enough flexibility to suit most applications. The reference voltage output can be programmed to a maximum of 5.0V in 2.5V increments.

The NJM79L18A is designed to require a minimum of external components in order to deliver the required power. It features an input voltage range from 2.7V to 44V and a quiescent current of only 5µA. The device also has a shutdown pin, which can be used to shut the device down when needed.

The NJM79L18A incorporates a high-speed internal current limit circuit which can protect the device from any overload. The internal thermal shutdown circuit is also incorporated to prevent overheating by regulating the output current when temperature gets too high. Overvoltage protection is also available, allowing the output voltage to be limited to avoid damage to the circuit.

NJM79L18A is incredibly versatile, it can be used in both AC and DC voltage applications. It can be used in audio products, such as amplifiers and receivers, or it can be used in apps where low noise levels and high precision power regulation are required, such as digital signal processors and microcontrollers. It can also be used in automotive applications and other high-reliability circuits.

In summary, the NJM79L18A voltage regulator is an efficient, low-cost solution for applications that require a linear voltage output with adjustable voltage range and reference voltage source. Its high-speed current limit and thermal protection make it reliable, while its minimal external components and low power consumption make it cost-effective. With its wide versatility, it is suitable for a variety of applications and is one of the most popular voltage regulators used today.
