LM337IMP/NOPB Description

Short technical summary and product information.

The LM337IMP/NOPB from Texas Instruments is an adjustable 3-terminal negative voltage regulator capable of supplying -1.5A or more currents over an output voltage range of -1.25V to -37V. It requires only two external resistors to set the output voltage and one output capacitor for frequency compensation.

This regulator features excellent regulation with a typical line regulation of 0.01%/V and load regulation of 0.3%. It offers a typical ripple rejection of 77dB and a temperature coefficient of 50ppm/°C. The device includes internal current limiting, thermal shutdown, and safe-area compensation, making it robust against overloads.

The LM337IMP/NOPB is supplied in a surface-mount SOT-223-4 package. It operates within a temperature range of -40°C to 125°C. This regulator is an ideal complement to adjustable positive regulators like the LM317.

Key electrical specifications include a 1.5A output current, adjustable negative output voltage from -1.25V to -37V, and protection features such as over-temperature and short-circuit protection.
