NTE1914
3 Terminal Positive Voltage Regulator
12V, 1A
Description:
The NTE1914 is a positive 3–terminal voltage regulator in a TO3 type package suitable for numerous
applications requiring up to 1A. One of these is local on card regulation, eliminating the distribution
problems associated with single point regulation. Other applications include; logic systems, instru-
mentation, HiFi, and other solid state lectronic equipment. Although designed primarily as a fixed volt-
age regulator, the NTE1914 can be used with external components to obtain adjustable voltages and
currents.

Note 2. All characteristics are measured with a 0.22µF capacitor across the input and a 0.1µF capac-
itor across the output. All characteristics except noise voltage and ripple rejection ratio are
measured using pulse tecniques (t

to changes in internal temperature must be taken into account separately.
