Description
The KA337 / LM337 are 3-terminal negative adjustable
regulators. They supply in excess of 1.5 A over an output
voltage range of -1.25 V to -37 V. These regulators
require only two external resistors to set the output volt-
age and employ current limiting, thermal overload protec-
tion, and safe area compensation.
