Package

The LM317MADTRKG is a linear voltage regulator IC packaged in a DPAK (TO-252) form factor. It is designed for surface mounting and commonly used in applications requiring adjustable output voltage regulation. The package provides efficient heat dissipation and is suitable for automated assembly processes.

Pinout

The LM317MADTRKG is a voltage regulator with a 3-pin configuration. It functions as an adjustable voltage regulator capable of providing output voltages ranging from 1.25V to 37V, depending on the external resistor configuration. The three pins are:
1. Input Pin: This pin receives the input voltage that needs to be regulated. It should be higher than the desired output voltage by a certain margin to ensure proper regulation.
2. Output Pin: The regulated output voltage is taken from this pin. The voltage level can be adjusted by varying the resistance connected between the output and adjust pins.
3. Adjust Pin: This pin is used to set the output voltage. By connecting external resistors between the adjust pin and the output pin, the output voltage can be finely tuned as per the requirements.
The LM317MADTRKG is commonly used in power supply circuits to provide a stable and adjustable output voltage.
