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 D Available in 2 Package Styles: NTE1869 (Giant TO92 Type) NTE1869SM (SOT-89 Surface Mount) Applications: D Car Stereo Equipment D Radio Cassette Recorder D Portable Stereo D Other General Electronic Equipment Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Input Voltage, VIN . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 36V Drive Current, ID . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30mA Input-Output Voltage Difference, VI-VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30V Power Dissipation, PD NTE1869 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 900mW NTE1869SM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -20 to +75C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +150C Recommended Operating Conditions: Supply Voltage Range, VIN . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.5V to 30V Rated Supply Voltage, VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.5V to 25V
