ON Semiconductor LM317CDR2G Adjustable Voltage Regulator

The LM317CDR2G is a versatile and robust adjustable voltage regulator designed and manufactured by ON Semiconductor, a leading name in energy-efficient innovations. This linear voltage regulator is capable of supplying more than 1.5A of load current with an output voltage adjustable over a 1.2 to 37 V range. It is a three-terminal positive regulator, which is available in the SMT (Surface-Mount Technology) DPAK package, making it suitable for automated assembly processes and compact circuit designs.

ON Semiconductor's LM317CDR2G is engineered for a wide range of applications, including local, on-card regulation. This regulator eliminates the distribution problems associated with single-point regulation. Each unit is exceptionally easy to use by including on the chip all the circuitry needed for a positive voltage regulator. The device features a thermal overload protection system that shuts down the output when the maximum operating temperature is exceeded. It also includes current limiting, which protects both the regulator and the connected circuitry from high current events.

The output voltage is set simply by adding two external resistors, which provides the user with great flexibility to tailor the output to the desired voltage level. This flexibility makes the LM317CDR2G an ideal choice for an array of electronic applications, from simple power supplies to complex automated systems. The device's ability to operate with an input-output differential of 1.2V at maximum load further enhances its versatility in various circuit configurations.

Key features of the LM317CDR2G include:

• Output Voltage Range Adjustable from 1.2V to 37V
• Output Current Greater Than 1.5A
• Thermal Overload Protection
• Short Circuit Protection
• Output Transistor Safe-Area Compensation
