NTE1930
Integrated Circuit
Positive Adjustable Voltage Regulator,
5V to 37V, 25mA
Description:
The NTE1928 is an adjustable positive voltage regulator in an 8鈥揕ead DIP type package that features
fast response to both load and line transients, freedom from oscillations with varying resistive and
reactive loads, and the ability to start reliabity on any load within rating. This device also contains a
biasing circuitry that removes any minimum load current requirement and at the same time reduces
standby current drain, permitting higher voltage operation.
