NTE NTE1916 Datasheet
NTE1916
3 Terminal Positive Voltage Regulator
15V, 1.5A
Description:
The NTE1916 is a positive 3–terminal voltage regulator in a TO3 type package suitable for numerous
applications requiring up to 1.5A. Current limiting is included to limit peak output current to a safe
value. Safe area protection for the output transistor is provided to limit internal power dissipation.
If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown
circuit takes over limiting die temperature.
Although designed primarily as a fixed voltage regulator , the NTE1916 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
≤ 10ms, duty cycle ≤ 5%). Output voltage changes due
w
to changes in internal temperature must be taken into account separately.
