NTE934
Integrated Circuit
Positive 3 Terminal Voltage Regulator
13.8V ±5%, 5A
Description:
The NTE934 positive 3 terminal voltage regulator is a monolithic integrated circuit in a TO3 type package designed for use in applcations 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. A hermetically sealed steel TO3 package is utilized for high reliability and low
thermal resistance. A low–noise temperature stable band–gap reference is the key design factor insuring excellent temperature regulation. 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 separately.
Note 3. BW = 10Hz to 100kHz.
Note 4. Ripple attenuation is specified for a 1Vrms, 120Hz, input ripple. Ripple attenuation is minimum of 60dB at 5V output and is 1dB less for each volt increase in the output voltage.
Note 5. VO = VC (1 + R1/R2)
R1 = Resistance from output to control
R2 = Resistance from control to common
