Description:
The NTE953 4−Terminal adjustable voltage regulator is designed to deliver continuous load currents
of up to 1.0A with a maximum input voltage of +40V. Output current capability can be increased to
greater than 1.0A through the use of one or more external transistors. The output voltage range is
5V to 30V. For systems requiring both a positive and negative, the NTE953 and NTE954 are excellent
for use as a dual tracking regulator with appropriate external circuitry.
