The LM337 series is a 3-terminal adjustable negative voltage regulator capable of supplying -1.5A output current over an adjustable voltage range of -1.2V to -37V. This regulator offers superior performance compared to standard fixed voltage regulators and is designed for easy use with only two external resistors needed for output voltage adjustment.
With excellent thermal regulation and low temperature coefficient, the LM337 provides better line and load regulation than typical fixed regulators. This makes it ideal for a variety of applications where negative voltage regulation is required, and the full overload protection ensures reliable and durable operation. The regulator is housed in a standard 3-lead transistor package, which is easy to handle and mount.
