Update: 28 September, 2023
The NCV4279B is a 5.0 V precision micropower voltage regulator with an output current capability of 150 mA. The output voltage is accurate within ±2.0% with a maximum dropout voltage of 0.6 V at 150 mA. It features low quiescent current, drawing only 90 μA with a 100 μA load. This part is ideal for battery operated microprocessor equipment. The microprocessor control logic includes an active RESET (with DELAY) and a FLAG monitor, which provides an early warning signal to the microprocessor of a potential impending RESET signal. The use of the FLAG monitor allows the microprocessor to finish any signal processing before the RESET shuts it down. The active RESET circuit operates correctly at an output voltage as low as 1.0 V. The RESET function is activated during the power up sequence or if the output voltage drops outside the regulation limits during normal operation. The reset threshold voltage can be adjusted by connecting an external resistor divider to the RADJ lead. The regulator is protected against reverse battery, short circuit, and thermal overload conditions. It is suitable for use in automotive environments, as it can withstand load dump transients. The device has also been optimized for EMC conditions.
