LM137K Description

Short technical summary and product information.

The LM137K from STMicroelectronics is a versatile 3-terminal adjustable negative voltage regulator. It is designed to supply currents in excess of 1.5 A over an output voltage range of -1.2 V to -37 V. The device is easy to use, requiring only two external resistors to set the output voltage.

 

Key electrical specifications 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. Protection features such as current limit and thermal overload protection are integrated onto the chip.

 

This regulator is supplied in a standard TO-3 package, suitable for through-hole mounting. The operating temperature range is -55°C to 150°C, making it suitable for demanding environments. The LM137K is designed for applications requiring stable and adjustable negative voltage outputs.
