NCV4299A Voltage Regulator Low-Dropout 150 mA The NCV4299A is a family of precision micropower voltage regulators with an output current capability of 150 mA. It is available in 5.0 V or 3.3 V output voltage. The output voltage is accurate within "2% with a maximum dropout voltage of 0.5 V at 100 mA. Low Quiescent current is a feature drawing only 65 mA with a 100 mA load. This part is ideal for any and all battery operated microprocessor equipment. The device features microprocessor interfaces including an adjustable reset output and adjustable system monitor to provide shutdown early warning. An inhibit function is available. With inhibit active, the regulator turns off and the device consumes less than 1.0 mA of quiescent current. The part can withstand load dump transients making it suitable for use in automotive environments.
