ONSEMI LM317MDTG Adjustable Voltage Regulator

The LM317MDTG is an adjustable three-terminal positive linear voltage regulator capable of supplying over 500 mA with an output voltage range from 1.2 V to 37 V. It is easy to use, requiring only two external resistors to set the desired output voltage. The device features internal current limiting, thermal shutdown, and safe area compensation, making it highly reliable and resistant to damage. Suitable for local and on-card regulation applications, it can also be configured as an adjustable switching regulator, a programmable output regulator, or a precision current regulator by connecting a fixed resistor between the adjustment and output terminals. The regulator includes internal thermal overload protection, short-circuit current limiting, and safe-area protection for the output transistor. It allows floating operation for high-voltage applications and eliminates the need for multiple fixed-voltage components. This device is Pb-free and ideal for power management and various electronic applications.
