The LM117/217/317 are monolithic integrated circuit voltage regulators designed to supply more than 1.5A of load current with an output voltage adjustable over a 1.2 to 37V range.
They are easy to use and eliminate the need for stocking many fixed regulators.
The regulators provide a complete series of protections, including current limiting, thermal shutdown, and SOA control.
They are designed for floating operation for high voltages and have a 0.1% line and load regulation.
The regulators provide internal reference voltage of 1.25V and can be used as precision current regulators.
They also provide a range of applications, including electronic shut-down regulators, battery chargers, and current limiters.
The regulators have various mechanical data and are available in different packages.
The document also includes electrical characteristics, thermal data, connection diagrams, and ordering numbers.
