The LM337L is an adjustable 3-terminal negative voltageregulator capable of supplying 100mA over a 1.2V to 37Voutput range. It is exceptionally easy to use and requiresonly two external resistors to set the output voltage. Furthermore,both line and load regulation are better than standardfixed regulators. Also, the LM337L is packaged in a standardTO-92 transistor package which is easy to use.
