The LM317MDTRK is an adjustable three-terminal positive-voltage regulator designed to supply more than 1A of load current with a 1.2V to 37V range of output voltage. It is available in standard TO-220 and D2Pak packages. It is a dual output voltage regulator, allowing for the ability to provide two different output voltages from a single device as well as the ability to down regulate a voltage source or use as a current limiter. The LM317MDTRK is a three-terminal regulator that can provide up to 1.5A of load current with a range of 1.2V to 37V.

The LM317MDTRK has a typical output voltage accuracy of 0.4% and line regulation of 0.03%/V, making it ideal for applications such as power supplies, voltage references, and adjustable power supplies. It also features an integrated thermal protection circuit, ensuring reliable operation and protection in case of overload.

The LM317MDTRK is ideal for a wide range of applications, such as:

• DC/DC converters
• Personal computers
• Notebooks and tablets
• Printers and fax machines
• Automotive applications
• Industrial instrumentation
• Medical equipment

The working principle of the LM317MDTRK is quite simple. Its internal circuitry is designed to sense the output voltage and regulate the current flow in order to maintain the desired output voltage. This is done via its feedback network comprising an adjustable potentiometer, an internal resistor and a voltage divider. The potentiometer determines the current flow, allowing for the adjustment of the output voltage. The voltage divider sets the feedback voltage, which is sensed by the regulator.

In summary, the LM317MDTRK is an adjustable three-terminal positive-voltage regulator capable of supplying up to 1.5A of load current with a 1.2V to 37V range of output voltage. It is suitable for a wide range of applications, such as DC/DC converters, personal computers, notebooks and tablets, printers and fax machines, automotive applications, industrial instrumentation and medical equipment. Its working principle is based on an adjustable potentiometer, an internal resistor and a voltage divider.
