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 com-

ponents to obtain adjustable voltages and currents.

Features:

D Output Current in Excess of 1.5A

D Internal Thermal Overload Protection

D 100% Thermal Limit Burn–In

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 (tw ≤ 10ms, duty cycle ≤ 5%). Output voltage changes due

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