3- TERMINAL ADJUSTABLE REGULATOR
Description
The GM317 is an adjustable 3-terminal positive voltage reg-
ulator capable of supplying in excess of 1.5 A over an out-
put voltage range of 1.2 V to 37 V. This voltage regulator is
exceptionally easy to use and requires only two external re-
sistors to set the output voltage. Further, it employs internal
current limiting, thermal shutdown and safe area compen-
sation, making it essentially blow-out proof.
The GM317 a wide variety of applications including local,
application, and on card regulation. This device can also
be used to make a programmable output regulator, or by
connecting a fixed resistor between the adjustment and out-
put. The GM317 can be used as a precise current regula-
tor.

* CIN is required if regulator is located an appreciable distance from power supply filter.
**CO is not needed for stability, however, it improve transient response.

Since IADJ is controlled to less than 100µA, the error associated with this term is negligible
in most applications.
