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.
