NTE1869 & NTE1869SM
Integrated Circuit
3 Terminal Variable Voltage Regulator
Description:
The NTE1869 and NTE1869SM are semiconductor integrated circuits designed for general鈥損urpose
output voltage regulation. A high鈥損erformance variable output voltage regulator with small input鈥搊ut-
put voltage differences can be made in combination with externally connected PNP transistors.
These devices include a reference voltage circuit, error amplifier, and driver, and the output voltage
can be set freely by externally connected resistors, and a small, compact power supply circuit can
be achieved making the device suitable for use in small electronic equipment, such as car stereo, ra-
dio cassette recorder and portable stereo equipment.
