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.

Features:

D Adjustable Output Current Up to 2A (Guaranteed Up to TJ = +150°C)

D Adjustable Output Voltage Down to 2.85V

D Input Overvoltage Protection (Up to 60V, 10ms)

D Short Circuit Protection

D Output Transistor S.O.A. Protection

D Thermal Overload Protection

D Low Bias Current On Regulation Terminal

D Low Standby Current Drain
