NCV8501 Series

Micropower 150 mA LDO Linear Regulators with ENABLE, DELAY, RESET

, and Monitor FLAG

The NCV8501 is a family of precision micropower voltage regulators. Their output current capability is 150 mA. The family has output voltage options for adjustable, 2 . 5 V, 3.3 V, 5.0 V, 8.0 V, and 10 V.

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 A with a 100 A 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

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 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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously . If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. *During the voltage range which exceeds the maximum tested voltage of V

Thermal dissipation must be observed closely.

, operation is assured, but not specified. Wider limits may apply.
