NTE1942
Integrated Circuit
Positive Adjustable Voltage Regulator,
2.85V to 36V, 2A
Description:
The NTE1942 is an integrated circuit for voltage and current programmable regulation. Current limit-
ing, power limiting, thermal shutdown, and input overvoltage protection (up to 60V) make the
NTE1942 virtually blowout proof. The NTE1942 can be used to replace fixed voltage regulators when
high output voltage precision is required.
