NTE933

Integrated Circuit

Positive 3 Terminal Voltage Regulator,

12V, 5A

Description:

The NTE933 is a 3 terminal fixed p ositive v oltage r egulator i n a TO3 type package designed for use in
applications requiring a well regulated p ositive o utput v oltage. Outstanding features include full power
usage up to 5A o f l oad c urrent, i nternal current limiting, thermal shutdown, and safe a rea p rotection o n
the chip, providing protection o f t he s eries p ass D arlington, u nder m ost o perating c onditions. Hermeti­cally sealed s teel p ackages a re u tilized f or h igh r eliability a nd low thermal r esistance. A low–noise tem­perature stable band–gap 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.

Note 2. Low duty cycle pulse testing with Kelvin connections required. Die temperature changes

must be accounted for separatly.
Note 3. BW = 10Hz to 100kHz.
Note 4. Ripple attenuation is specified for a 1Vrms, 120Hz, input ripple. Ripple attenuation is mini-

mum of 60dB at 5V output and is 1dB less for each volt increase in the output voltage.
