3 Description

The LM237 and LM337 are adjustable 3-terminal

negative-voltage regulators capable of supplying in

excess of –1.5 A over an output voltage range of –1.2

V to –37 V. They require only two external resistors

to set the output voltage and one output capacitor for

frequency compensation.
