Description

The LM337 series are adjustable 3-terminal

negative voltage regulators capable of supplying

in excess -1.5 A over a -1.2 to -37 V output

voltage range. They are exceptionally easy to use

and require only two external resistors to set the

output voltage. Further, both line and load

regulation are better than standard fixed

regulators. Also, LM337 regulators are supplied in

standard transistor packages which are easily

mounted and handled. In addition to higher

performance than fixed regulators, the LM337

series offer full overload protection available only

in integrated circuits. Included on the chip are
