NTE1918
3 Terminal Positive Voltage Regulator
15V, 3A
Description:
The NTE1918 is a positive 3–terminal voltage regulator in a TO3 type package capable of driving
loads in excess of 3A. This device employs internal current limiting, thermal shutdown, and safe–area
compensation.
Although designed primarily as a fixed voltage regulator, the NTE1918 can be used with external com-
ponents to obtain adjustable voltages and currents.
Features:
D Output Current in Excess of 3A
D Power Dissipation: 30W
D Internal Thermal Overload Protection
D Output Transistor Safe Area Protection
D Internal Short Circuit Current Limit
D No External Components Required

Note 2. Load and line regulation are specified at constant junction temperature. Change in V_O due
to heating effects must be taken into account separately. Pulse testing with low duty cycle is
used.
