Description
The KA337 is a 3-terminal negative adjustable regulator. It
supply in excess of 1.5A over an output voltage range
of -1.2V to - 37V. This regulator requires only two external
resistor to set the output voltage. Included on the chip are
current limiting, thermal overload protection and safe area
compensation.
