The regulator is guaranteed to supply 200mA of output current. 25V to 37V. Integrated Circuit 3–Terminal Positive Voltage Regulator, 5V The NTE960 fixed–voltage regulator is a monolithic integrated circuit in a TO220 type package de-signed for use in a wide variety of applications including local, on–card regulation. A power converter IC accepts the dc input and produces a dc output or controls external power output semiconductor switches to produce a dc output. 5v voltage regulator circuit
