This is a 5.0V precision micropower voltage regulator with 150mA output current capability. The output voltage accuracy is ±2.0% with a maximum dropout voltage of 0.6V at 150mA. It can output 150mA current and is especially suitable for any battery-powered microprocessor equipment. Microprocessor control logic includes an active RESET (with DELAY) and a FLAG monitor that 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 1.0V. 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 an 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. The device has also been optimized for EMC conditions.
