The LM137K is a versatile adjustable 3-terminal negative voltage regulator capable of supplying over 1.5A within an output voltage range of -1.2V to -37V. It is designed for ease of use, requiring only two external resistors to set the output voltage. This regulator provides superior line and load regulation compared to standard fixed regulators.
Key electrical characteristics include a typical ripple rejection of 77 dB, typical load regulation of 0.3%/V, and typical line regulation of 0.01%/V. The device also features excellent thermal regulation at 0.002%/V and a temperature coefficient of 50 ppm/°C.
Designed with integrated circuit overload protection, the LM137K includes current limiting, thermal overload protection, and safe area protection, all of which remain functional even if the adjustment terminal is disconnected. It is supplied in a standard TO-3 package, suitable for through-hole mounting.
This adjustable negative voltage regulator is ideal for applications requiring precise and stable negative voltage outputs, such as power supplies, battery chargers, and active regulators.
