TECHNICAL DATA
THREE-TERMINAL ADJUSTABLE
OUTPUT POSITIVE VOLTAGE REGULATORS
KK317
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.
