LM217K is a three-terminal adjustable regulator that features adjustable current limiting and thermal overload protection. Capable of supplying in excess of 1.5A output current, the LM217K is available in several output voltage options. Additionally, its adjustable output voltage makes it an ideal choice for a variety of applications.

The LM217K has a wide input voltage range of 8V to 40V and can be used to regulate any voltage within that range. It consists of an internal series pass element, an integrated error amplifier, and a floating current source along with other circuitry that is required to achieve a high current output stage.

The LM217K has two major components which contribute to its main functions: the voltage regulator and the current regulator. The voltage regulator uses an feedback voltage divider to provide a stable output voltage. The current regulator limits the output current to the recommended value.

The LM217K can be easily configured to work in applications such as powering digital logic, powering low-voltage DC motors and solenoids, adjusting the speed of DC motors, controlling LED\'s, providing power for battery charging, and protecting sensitive circuits from high-voltage surges.

The LM217K\'s adjustable current limiting feature allows it to be used in applications such as LED dimming and controlling the speed of DC motors. It prevents the output current from exceeding the set limit and hence protects the connected circuit from being overloaded and provides reliable operation. The LM217K also features an adjustable thermal protection circuit which monitors the temperature of the device and limits the output current to prevent device damage due to overheating.

The LM217K has an adjustable output voltage of 1.2V to 37V. The output voltage can be easily adjusted by setting the divider resistors between the output and the adjustment pins. It offers up to 1.5A continuous output current, but it can be increased up to 3A with proper thermal management.

The LM217K has several protection features built-in for improved operation and longer life. It includes protection from over-temperature, over-current, and over-voltage. It also has an internal short-circuit limiter to protect the device and the connected load.

The LM217K is available in a small package and is ideally used in space-critical designs. The device is designed to operate in the -40°C to + 85°C temperature range. It is also RoHS compliant and completely compatible with lead-free manufacturing processes.
