NTE1925
3 Terminal Negative Voltage Regulator
鈥?8V, 1.5A
Description:
The NTE1925 is a negative 3鈥搕erminal voltage regulator in a TO3 type package suitable for numerous
applications including local, on鈥揷ard regulation requiring up to 1.5A. This device features thermal
shutdown and current limiting making the NTE1925 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.
