Integrated Circuit
Positive Adjustable Voltage Regulator,
5V to 37V, 25mA
Description:
The NTE1928 is an adjustable positive voltage regulator in an 8–Lead 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.
Features:
D Output Voltage Adjustable from 5V to 37V
D Output Currents in Excess of 10A Possible by Adding External Transistors
D Load Regulation Better than 0.1%, Full Load with Current Limiting
D DC Line Regulation Guaranteed at 0.03%/V
D Ripple Rejection on 0.01%V

Note 1. The maximum junction temperature of the NTE1930 is 100°C. For operation at elevated
temperatures, this device must be derated based on a thermal resistance of 138°C/W junc-
tion to ambient, or 25°C/W junction to case.

Note 2. Unless otherwise specified, these specifications apply for temperatures within the operating
temperature range, for input and output voltages within the range given, and for a divider
impedance seen by the feedback terminal of 2kΩ. Load and line regulation specifications
are for a constant junction temperature. Temperature drift effects must be taken into account
separately when the unit is operating under conditions of high dissipation.
Note 3. The output currents given, as well as the load regulation, can be increased by the addition
of external transistors. The improvement factor will be roughly equal to the composite cur-
rent gain of the added transistors.
Note 4. With no external pass transistor.
