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 load regulation of 0.3%/V and a typical line regulation of 0.01%/V. It also features a ripple rejection of 77 dB and a temperature coefficient of 50 ppm/°C. The device includes built-in current limiting, thermal overload protection, and safe area protection, ensuring robust operation even under fault conditions.
The LM137K is available in a TO-3 package, suitable for through-hole mounting. Its design makes it ideal for a wide range of applications requiring stable and adjustable negative voltage outputs.
