The NTE1929 is an adjustable 3--terminal positive voltage regulator in a TO220 package capable of supplying in excess of 3A over an output voltage range of 1.2V to 33V. This device employs internal current limiting, thermal shutdown, and safe-area compensation making it essentially blow--out proof. The NTE1929 serves a wide variety of applications including local, on-card regulation. This device
also makes an especially simple adjustable switching regulator, a programmable output regulator and can also be used as a precision current regulator.

* Thermal resistance evaluated measuring the hottest temperature on the die using an infrared scanner. This method of evaluation yields very accurate thermal resistance values which are conservativeompared to other measurement techniques. ** The average die temperature is used to derive the value of thermal resistance junction to case (average).
