NTE1923
3 Terminal Negative Voltage Regulator
–18V, 1.5A
Description:
The NTE1923 is a negative 3–terminal voltage regulator in a TO3 type package suitable for numerous
applications including local, on–card regulation requiring up to 1.5A. This device features thermal
shutdown and current limiting making the NTE1920 remarkably rugged.
Although designed primarily as a fixed voltage regulator, this device can be used with external compo-
nents to obtain adjustable voltages and currents.
Features:
D Internal Thermal Overload Protection
D Output Transistor Safe Area Protection
D Internal Short Circuit Current Limit
D No External Components Required
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)

Note 1. Load and line regulation are specified at constant junction temperature. Change in VO due
to heating effects must be taken into account separately. Pulse testing with low duty cycle is
used.
