TS317 3-Terminal Adjustable Positive Voltage Regulator TO-220 TO-263 TO-252 SOT-223 2 Pin Definition: (D PAK) (DPAK) 1. Adjustable 2. Output 3. Input Heatsink is connected to Pin 2 General Description The TS317 is adjustable 3-terminal positive voltage regulator capable of supplying in excess of 1.5A over an output voltage range of 1.25 V to 37 V. This voltage regulator is exceptionally easy to use and require only two external resistors to set the output voltage. Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow-out proof. Features Standard Application Circuit Output Voltage Range 1.25 to 37V Output current - TO-220/TO-263 up to 1.5A - TO-252/SOT-223 up to 500mA Eliminates Stocking Many Fixed Voltages Internal Thermal Overload Protection Current Limit Constant with Temperature Output transistor safe-area compensation Output voltage offered in 4% tolerance Floating Operation for High Voltage Applications Cin is required if regulator is located an appreciable Ordering Information distance from power supply filter. Co is not needed for stability, however, it does improve Part No. Package Packing transient response.

T to T = 0C to +125C, Pmax is internally limited LOW HIGH 2. Load and line regulation are specified at constant junction temperature. Changes in V due to heating O effects must be taken into account separately. Pulse testing with low duty cycle is used. 3. Cadj, when used, is connected between the adjustment pin and ground. 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. 4. Power dissipation within an IC voltage regulator produces a temperature gradient on the die, affecting individual IC components on the die. These effects can be minimized by proper integrated circuit design and layout techniques. Thermal Regulation in the effect of these temperature gradients on the output voltage and is expressed in the percentage of output change per watt of power change in a specified time.
