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.

Vout = 1.25 V * (1 + R2 / R1 ) + Iadj_j * 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. 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.
