Ordering Information

Part No. Operating Temp. Package TS317CZ TO-220 TS317CM TO-263 TS317CP TO-252 TS317CW -20 ~ +150oC SOT-223 Standard Application Vout = 1.25 V * (1 + R2 / R1 ) + Iadjj * R2 Since I Adj 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. T he input voltage must remain ty pically 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.

Changes in V O 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. 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. 6. Cadj, when used, is connected between the adjustment pin and ground. TS317 2-8 2003/12 rev. D
