onsemi Voltage Regulators - Linear NCV4279BDWR2G

The NCV4279BDWR2G is a 5.0 V linear voltage regulator designed for micropower applications, capable of delivering an output current of 150 mA. It features a precision output voltage accuracy of ±2.0% and a maximum dropout voltage of 0.6 V at full load. The device operates with a low quiescent current of 90 µA, making it suitable for battery-operated microprocessor equipment. This regulator includes an active RESET function with a delay feature, which activates during power-up or when the output voltage falls outside regulation limits. Additionally, it has a FLAG monitor output that provides an early warning signal to the microprocessor, allowing it to complete processing before a reset occurs. The RESET threshold voltage can be adjusted using an external resistor divider. The NCV4279BDWR2G is designed with robust protection features, including reverse battery protection, short circuit protection, and thermal overload protection. It can withstand load dump transients, making it appropriate for automotive applications. The device is available in multiple package options, including SOIC-20WB, and is offered in Pb-free versions.
