onsemi Voltage Regulators - Linear NCV4264-2CST33T3G

The NCV4264-2CST33T3G is a low dropout linear voltage regulator designed to provide a fixed output voltage of 3.3 V with an output current capability of up to 100 mA. It features a quiescent current of 33 µA, making it suitable for applications where low power consumption is critical. The device operates over a wide input voltage range of 4.5 V to 45 V and maintains an output voltage accuracy of ±2.0% across the full temperature range. This regulator includes built-in protection against input transients up to 45 V, reverse input supply, output overcurrent, and thermal overload, eliminating the need for external components for these features. The maximum dropout voltage is specified at 500 mV under a 100 mA load, ensuring efficient operation. The NCV4264-2C is AEC-Q100 qualified, making it suitable for automotive applications. It is packaged in a SOT-223 case and is a lead-free device.
