The NJM78L18L2A is a voltage regulator from the Linear series of voltage regulators offered by NJR. This particular regulator functions in two different modes — a low dropout (LDO) mode, and a quasi-regulated (QR) mode. The device is capable of delivering +/-2A of current and is suitable for use in a wide variety of applications.

In LDO mode, the NJM78L18L2A regulates the output voltage by varying the current in the sense resistor connected at the device\'s output pin. This allows for a wide range of adjustable output voltages without the need for external components, up to a maximum of 18V. The device is capable of handling both low current and large current applications.

In the other mode, known as the "quasi-regulated" mode, the device regulates the output voltage by using an internal reference voltage. This is done by varying the current in the resistors connected to the input and output pins of the device. The use of this mode allows for a more efficient regulation over a wider range of input voltages than the LDO mode, but with a more limited output voltage range. This mode is used for applications that require more precision, such as microprocessor and memory supplies.

The NJM78L18L2A is designed for applications that require low noise, fast regulation and high efficiency performance, such as notebook computers and battery-powered electronic devices. The device is also suitable for use in hand-held devices and automotive applications.

NJR\'s NJM78L18L2A is a versatile, efficient, and cost-effective voltage regulator. With options for LDO and QR mode and adjustable output voltages, the NJM78L18L2A is a great choice for use in a wide variety of applications. Furthermore, its low noise, fast regulation and high efficiency performance make it an ideal choice for those who need a reliable and versatile voltage regulator.
