NTE NTE1869, NTE1869SM Datasheet
NTE1869 & NTE1869SM
Integrated Circuit
3 Terminal Variable Voltage Regulator
Description:
The NTE1869 and NTE1869SM are semiconductor integrated circuits designed for general–purpose
output voltage regulation. A high–performance variable output voltage regulator with small input–output 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, radio cassette recorder and portable stereo equipment.
Features:
D Wide Operating Voltage Range: VIN = 3.5V to 36V, VO = 1.5V to 33V
D Output Voltage can be Freely Set by Externally Connected Resistors
D Built–In ASO Protection and Thermal Cutoff Circuits
