1 / 8 page TS317 3-Terminal Adjustable Output Positive Voltage Regulator Output Voltage Range From 1.25V to 37V Output Current up to 1.5A 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. The TS317 is offered in 3-pin TO-220, TO-263, TO-252 and SOT-223 package. Features Output current up to 1.5A * TO-220/TO-263 for 1.5A * TO-252/SOT-223 for 500mA Output Adjustable between 1.25 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 Eliminates Stocking Many Fixed Voltages Output voltage offered in 4% tolerance Ordering Information Part No. Operating Temp. Package TS317CZ TO-220 TS317CM TO-263 TS317CP TO-252 TS317CW -20 ~ +150 oC SOT-223 Standard Application Vout = 1.25 V * (1 + R2 / R1 ) + Iadjj * R2 Since IAdj is controlled to less than 100 µA, the error associated with this term is negligible in most applications A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point on the Input ripple voltage. * = Cin is required if regulator is located an appreciable distance from power supply filter. ** = Co is not needed for stability; however, it does improve transient response.
