NTE923 & NTE923D
Integrated Circuit
Precision Voltage Regulator
Description:
The NTE923 and NTE923D are voltage regulators designed primarily for series regulator applica-
tions. By themselves, these devices will supply output currents up to 150mA; but, external transistors
can be added to provide any desired load current. The circuits feature extremely low standby current
drain, and provision is made for either linear or foldback current limiting.
These devices are also useful in a wide range of other applications such as shunt regulators, current
regulators, and temperature controllers.
Features:
D 150mA Output Current without External Pass Transistor
D Output Currents in Excess of 10A Possible by Adding External Transistors
D Input Voltage: 40V Max
D Output Voltage Adjustable from 2V to 37V
D Can be Used as Either a Linear or a Switching Regulator
