NTE961
Linear Integrated Circuit
Voltage Regulator, Negative, 5V, 1A
Description:
The NTE961 voltage regulator employs current limiting, thermal shutdown, and safearea com-
pensation which makes it remarkably rugged under most operating conditions. With adequate heat
sinking they can deliver output currents in excess of 1.0 amperes.

) is 50
C/W (no heat sink) and 5
C/W (infinite heat sink).

Note 2. Regulation is measured at a constant junction temperature by pulse testing with a low duty
cycle. Changes in output voltage due to heating effects must be taken into account.
