¡El NCV8504 is a family of precision micropower voltage regulators. Their output current capability is 400 mA. ¡El family has output voltage options for Adjustable, 2.5 V, 3.3 V and 5.0 V. ¡El output voltage is accurate within ± 2.0% with a maximum dropout voltage of 0.6 V at 400 mA. Low quiescent current is a feature drawing only 100 μA with a 100 μA load. This part is ideal for any and all battery operated microprocessor equipment. Microprocessor control logic includes an active RESET (with DELAY). ¡El active RESET circuit operates correctly at an output voltage as low as 1.0 V. ¡El RESET function is activated during the power up sequence or during normal operation if the output voltage drops below the regulation limits. ¡El reset threshold voltage can be decreased by the connection of external resistor divider to RADJ lead. ¡El general use comparator (FLAG/Monitor) is referenced to a temperature stable voltage and provides 1 mA of drive current at its open collector output. ¡El regulator is protected against reverse battery, short circuit, and thermal overload conditions. ¡El device can withstand load dump transients making it suitable for use in automotive environments. The device has also been optimized for EMC conditions.
