NTE7107
Integrated Circuit
Switching Regulator, 2.5A
Description:
The NTE7107 is a monolithic power regulator in a 7−Lead Staggered SIP type package delivering
2.5A at a voltage variable from 5V to 40V in step down configuration. Features of this device include
current limiting, soft start, thermal protection, and 0 to 100% duty cycle for continuous operation
mode. Efficient operation at switching frequencies up to 150kHz allows a reduction in the size and
cost of external components.
