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 requiring a well regulated positive output voltage. Outstanding features include full power
usage up to 3A 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–noise tem-
perature 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 1. Short circuit protection is only assured to VINmax. In case of short circuit, with input–output
voltages approaching VINmax, regulator may require the removal of the input voltage to re-
start.

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.
