NTE933
Integrated Circuit
Positive 3 Terminal Voltage Regulator,
12V, 5A
Description:
The NTE933 is a 3 terminal fixed positive voltage regulator in a TO3 type package designed for use in
applications requiring a well regulated positive output voltage. Outstanding features include full power
usage up to 5A of load current, internal current limiting, thermal shutdown, and safe area protection on
the chip, providing protection of the series pass Darlington, under most operating conditions. Hermeti-
cally sealed steel packages are utilized for high reliability and low thermal resistance. A low鈥搉oise tem-
perature stable band鈥揼ap reference is the key design factor insuring excellent temperature regulation
of the NTE933. This coupled to a very low output impedance insures superior load regulation.
