The NTE966 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. This regulator em-
ploys internal current limiting, thermal shutdown, and safe−area compensation. With adequate heat-
sinking it can deliver output currents in excess of 1.0 ampere.

... Normally good construction tech- niques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense leads. Current Regulator NTE966 0.33µF The NTE966 regulator can also be used as a current source when connected as above. Resistor R determines the current as follows ...

... Input R NTE966 1.0µF The NTE966 can be current bolosted with a PNP transistor. The NTE219 provides current to 5 amperes. Resistor R in conjunction with the V of the PNP determines when the pass transistor BE begins conducting; this circuit is not short−circuit proof. Input−output differential voltage minimum is increased the pass transistor ...
