TS317L

The TS317L is adjustable 3-terminal positive voltage regulator capable of supplying in excess of 100mA over an output voltage range of 1.25 V to 37 V. This voltage regulator TS317L 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.

Besides replacing fixed regulators, the TS317L is useful in a wide variety of other applications. Since the regulator is "floating " and sees only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input-to-output differential is not exceeded.

Also, TS317L makes an especially simple adjustable switching regulator, a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the TS317L can be used as a precision current regulator. Supplyies with electronic shutdown can be achieved by clamping the adjustment terminal to ground which programs the output to 1.25V where most loads draw little current.

The TS317L is offered in 3-pin TO-92 and SOP-8 package.
