LM337H Description

Short technical summary and product information.

The Texas Instruments LM337H is a versatile adjustable 3-terminal negative voltage regulator. It is capable of supplying up to 500mA of output current over an adjustable output voltage range from -1.25V to -37V. This device requires only two external resistors to set the output voltage and one output capacitor for frequency compensation.

 

The LM337H features internal current limiting, thermal shutdown, and safe-area compensation, making it robust against overloads. Its typical line regulation is 0.01%/V and load regulation is 0.3%, with a ripple rejection of 77dB at 120Hz. The operating temperature range is -55°C to 150°C.

 

This regulator is housed in a TO-3 metal can package and is designed for through-hole mounting. It is an ideal complement to adjustable positive regulators like the LM317.

 

Key electrical characteristics include an output voltage range of -1.25V to -37V and a maximum output current of 500mA. The device also provides protection features such as over-temperature and short-circuit protection.
