ONSEMI LM317LDR2G Adjustable Voltage Regulator

The LM317LDR2G is an adjustable 3-terminal positive voltage regulator capable of delivering over 100mA current with an output voltage range of 1.2V to 37V. It is easy to use, requiring only two external resistors to set the desired output voltage. The device features internal thermal shutdown, current limiting, and safe area protection, making it highly reliable and resistant to damage. Suitable for various applications including local regulation on PCBs, it can also be configured as a programmable voltage regulator or a precision current regulator by connecting a fixed resistor between the adjustment and output pins. Additional features include internal thermal overload protection, short-circuit current limiting, safe-area compensation for the output transistor, and floating operation for high-voltage applications, eliminating the need to stock multiple fixed-voltage regulators.
