The MC33275D-5.0 is a low dropout linear voltage regulator from the PMIC Voltage Regulators – Linear category. It has a working voltage from 4.5 V to 15 V, with a maximum quiescent current of 4 mA. This product is suitable for applications such as battery-powered devices, automotive systems, and portable consumer electronics.

The MC33275D-5.0 is an integrated Linear Voltage Regulator (LVR) with a current limit of 1.0 A and an output voltage set to 5.0 V. The integrated LVR provides basic protection against reverse battery connection and thermal shutdown protection to prevent regenerative effects triggered by excessive output current liment. The device has a high efficient thermal design. It can manage with extreme temperatures up to -40°C and 125°C, and taking into account the high-temperature derating curve of the device can operate up to 150°C.

The MC33275D-5.0 supports load transient protection, allowing the regulator to constantly monitor the output load current and respond to sudden changes in load current. The monitor also takes into account the output voltage regulation to guarantee continuous voltage regulation with different load changes. The regulator also limits the output current to avoid overloading the system and creating an overload-thermal protection situation.

The MC33275D-5.0 has a high standby current of 5 mA, which results in improved power efficiency when the device is in low-power mode. It also offers low noise operation, a built-in regulation bypass for bypassing the internal regulation and connecting an external regulator, as well as a soft-start feature to reduce inrush current. Additionally, the device combines a fast output voltage slew, 0.001V/μs, with very low dropout voltage, typically 0.28V at 1.0A.

The MC33275D-5.0 can be used in various applications, such as portable consumer electronics, automotive systems, and battery powered devices, where it can provide reliable power regulation and efficient power management. Its wide input voltage range, low quiescent current, low dropout voltage performance, as well as its power saving features, make it an ideal solution for energy saving applications.

In summary, the MC33275D-5.0 is a low dropout linear voltage regulator, which provides protection against reverse battery connection, thermal shutdown protection to prevent regenerative effects, low dropout voltage, and fast output voltage slew. This device is primarily used in portable consumer electronics, automotive systems, and battery powered devices, where it provides reliable power regulation, power efficiency, and power management to the specific application.
