NTE932
Integrated Circuit
3Terminal Positive Voltage Regulator
5V, 5A
Description:
The NTE932 is a 3terminal 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 o he series pass Darlington, under most operating condi-
tions. A lownoise, 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 regula-
tion.

Note 2. Low duty cycle pulse testing with Kelvin connections required. Die temperature changes
must be accounted for separately.
Note 3. Ripple attenuation is specified for a 1V
rms
, 120Hz, input ripple. Ripple attenuation is
minimum of 60dB at 5V output and is 1dB less for each volt increase in the output volt-
age.
