LM337IMPX Description

Short technical summary and product information.

The LM337IMPX from Texas Instruments is an adjustable 3-terminal negative voltage regulator. It is capable of supplying currents of 1.5A or more over an output voltage range of -1.25V to -37V. This regulator requires only two external resistors to set the output voltage and one output capacitor for frequency compensation.

 

Key electrical specifications include a typical line regulation of 0.01%/V and a typical load regulation of 0.3%. It offers a ripple rejection of 77dB and a temperature coefficient of 50ppm/°C. The device operates within a temperature range of -40°C to 125°C.

 

Protection features include internal current limiting and thermal shutdown, making it robust against overloads. The LM337IMPX is supplied in a SOT-223-4 package, suitable for surface mount applications. It is designed as a complement to adjustable positive regulators.

 

This component is ideal for applications requiring a stable, adjustable negative voltage supply. Its adjustable nature and built-in protection make it a versatile choice for various power management designs.
