NCV8503 Series
Micropower 400 mA LDO Linear Regulators
with ENABLE, DELAY,
Adjustable RESET, and
General Use Comparator
The NCV8503 is a family of precision micropower voltage regulators. Their output current capability is 400 mA. The family has output voltage options for Adjustable, 2.5 V, 3.3 V and 5.0 V.
The 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 less than 1.0 mA with ENABLE = 0 V. With ENABLE = 5.0 V, the part only draws 200 mA with 100 mA load. This part is ideal for any and all battery operated microprocessor equipment.
Microprocessor control logic includes an active RESET (with DELAY).
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 during normal operation if the output voltage drops below the regulation limits.
The reset threshold voltage can be decreased by the connection of external resistor divider to RADJ lead.
The general use comparator (FLAG/Monitor) is referenced to a temperature stable voltage and provides 1.0 mA of drive current at its open collector output.
The regulator is protected against reverse battery, short circuit, and thermal overload conditions. The device can withstand load dump transients making it suitable for use in automotive environments. The device has also been optimized for EMC conditions.
