The LR645N8-G is a 3-terminal low dissipation adjustable linear regulator. When used it has a wide range of applications and working principles that make it indispensable for many design solutions.

The device can supply a constant output voltage with 5.0V to 32V in the range of operating input voltage up to 45V. It can also deliver a very low quiescent current in the range of 10 μA to 200 μA while providing output power up to 1.8W. This makes the device ideal for small, low-power applications.

The LR645N8-G features a wide voltage range, fast transient response, excellent line and load-regulation over temperature, ultra-low shutdown current, and excellent temperature stability.

The LR645N8-G operates on a self-biasing concept, whereby the output voltage is pre-programmed at the factory by either external resistors or programmed capacitor-resistor networks, depending on the application.

The LR645N8-G is able to adjust its output voltage over a wide range within a pre-defined band. This makes it ideal for applications that require voltage or power supply stability with a wide variety of loads. It can also be set to precise voltage levels with trimmer resistors or potentiometers to precise the output voltage to meet specific application needs.

The device has excellent thermal protection features, with a thermal shutdown circuit to protect it from damage due to over temperature. Its high reliability performance is further improved with a low thermal resistance junction-to-case design.

The LR645N8-G can be used to protect microcontrollers, RAM, and other IC supplies against transients and overstress conditions, and can be set up to provide linear regulation, soft-start capabilities and sequencing of multiple regulators. It also features an internal current limiter to prevent excessive output current.

Overall, the LR645N8-G is a highly versatile and reliable device that can be used in a wide variety of applications. It can be used for general purpose voltage regulation, for voltage or power supply stabilization, and for protecting integrated circuits from overstress conditions. With its low power consumption and fast transient response, it is an ideal choice for low-power applications.
