TECHNICAL DATA

THREE-TERMINAL ADJUSTABLE

KK317

OUTPUT POSITIVE VOLTAGE REGULATORS

The KK317 is adjustable 3-terminal positive voltage

regulator capable of supplying in excess of 1.5 A over an

output voltage range of 1.2 V to 37 V. These voltage

regulator is exceptionally easy to use and require only two

external resistors to set the output voltage. Further, it employ

internal current limiting, thermal shutdown and safe area

compensation, making

them essentially blow-out proof.

The KK317 serve a wide variety of applications to

make a programmable output regulator, or by connecting a

fixed resistor between the adjustment and output, the KK

317 series can be used as a precision current requlator.
