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
● 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
distance from power supply filter.
Co is not needed for stability, however, it does improve
transient response.
Vout = 1.25 V(1 + R2 / R1 ) + I_AdjR2
Since I_Adj is controlled to less than 100 µA, the error
associated with this term is negligible in most
applications
