TECHNICAL DATA THREE-TERMINAL ADJUSTABLE 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. • Output Current in Excess of 1.5 Ampere • Output Adjustable between 1.2 V and 37 V • Internal Thermal Overload Protection • Internal Short - Circuit Current Limiting Constant with Temperature • Output Transistor Safe-Area Compensation • Floating Operation for High Voltage Applications • Standard 3-lead Transistor Packages • Eliminates Stocking Many Fixed KK317 TO-220 AB Pin 1.
