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.

Standard Application

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.
