NCV8502: Linear Voltage Regulator, LDO, 150 mA, with Delay, Adustable Reset and Monitor Flag

Product Description
The NCV8502 is a family of precision micropower voltage regulators with 150mA output current capability. The family has output voltage options for adjustable, 2.5 V, 3.3 V, 5.0 V, 8.0 V, and 10 V that are accurate within ±2.0%. Maximum dropout voltage reached 0.6 V at full load.
Low quiescent current is a feature drawing only 90µA with a 100µA load. This part is ideal for 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 shuts the microprocessor 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 during normal operation if the output voltage drops outside the regulation limits.
The reset threshold voltage can be decreased by the connection of external resistor divider to RADJ lead.

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.
