Integrated Circuit
Positive 3 Terminal Voltage Regulator,
12V, 3A
Description:
The NTE1912 is a 3 terminal fixed positive voltage regulator in a TO3 type package designed for use
in applications r equiring a w ell regulated positive o utput v oltage. Outstanding f eatures i nclude f ull power
usage up to 3A 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 NTE1912. 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.
