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.
Features:
D Output Current in Excess of 1.0 Ampere
D No External Components Reguired
D Internal Thermal Overload Protection
D Internal Short−Circuit Current Limiting
D Output Transistor Safe−Area Compensation
