The NCV8504 is a family of precision micropower voltage regulators with an output current capability of 400mA. The family offers options for adjustable, 2.5V, 3.3V, and 5.0V output voltages. The output voltage is accurate within ±2.0% and has a maximum dropout voltage of 0.6V at 400mA. It features low quiescent current of only 100µA with a 100µA load, making it ideal for battery-operated microprocessor equipment. The microprocessor control logic includes an active RESET circuit with a delay. The RESET function operates correctly even at an output voltage as low as 1.0V. The reset threshold voltage can be decreased by connecting an external resistor divider to the RADJ lead. The general use comparator (FLAG/Monitor) is referenced to a temperature stable voltage and provides 1mA of drive current at its open collector output. The regulator is protected against reverse battery, short circuit, and thermal overload conditions. It can withstand load dump transients, making it suitable for automotive environments. The device has also been optimized for EMC conditions.
The NCV8504 family provides precision micropower voltage regulation for battery‑operated microprocessor equipment. It offers 400 mA output current, selectable output voltages (adjustable, 2.5 V, 3.3 V, 5.0 V), and a low quiescent current of 100 µA. Features include an active RESET with delay, a general‑use comparator, and robust fault protection (reverse battery, short‑circuit, thermal overload).
The device is qualified for automotive environments, with a peak transient voltage rating of 60 V and an input voltage range of –15 V to 45 V. Detailed electrical characteristics, pin descriptions, and typical performance graphs are provided for both adjustable and fixed‑output versions.
