KODENSHI KK317

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

(3) Load and line regulation are specified at constant junction tempereture. Changes in Vo due to heating effects must
be taken into account separately. Pulse testing with low duty cycle is used.
(4) Selected devices with tightened tolerance reference voltage available.
(5) Cadj , when used, connected between the adjustment pin and ground.
(6) Since Long - Term Stability cannot be measured on each device before shipment, this specification is an
engineering estimate of average stability from lot to lot.
