The NCV4279B is a 5.0 V precision micropower voltage regulator. The output current capability is 150 mA. The output voltage is accurate within 2.0% with a maximum dropout voltage of 0.6 V at 150 mA. Low quiescent current is a feature drawing only 90 mA with a 100 mA load. This part is ideal for any and all battery operated microprocessor equipment. Microprocessor control logic includes an active RESET (with DELAY), and a FLAG monitor which can be used to provide 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 s huts the microprocessor down.
