Application Field

The AP7361-33ER-13 is primarily designed for use in embedded systems, such as smartphones, tablets, and other portable electronics. The device is well suited for applications with low quiescent current and applications where a high output current is required. Examples of typical applications include powering the core voltage for microprocessors and other logic circuits, powering on and off the charge pumps, and providing a regulated output voltage for other components in the system. The high output current capability of the device makes it suitable for applications such as powering high-powered LED displays.

Working Principle

The AP7361-33ER-13 is a linear regulator, meaning that the device operates by adjusting the output voltage according to the input voltage. The voltage regulator works by using a pass element, usually a field-effect transistor (FET), to control the amount of current that flows through the device. The output voltage of the device is compared to a reference voltage and a feedback loop is used to adjust the amount of FET current to maintain the output voltage at the desired level.The AP7361-33ER-13 has an adjustable output voltage range from 0.7V to 2.6V, and the device can deliver up to 1.5A of current. The device also features a temperature-compensated precision voltage reference, a programmable current limit, and a thermal shutdown feature. The device is also capable of operating from a wide input voltage range from 2.3V to 5.5V. The device is protected against short circuit and over-current conditions and the device has an enable/shutdown pin which can be used to turn the device on and off.

Conclusion

The AP7361-33ER-13 is a linear voltage regulator with a wide input voltage range and an adjustable output voltage range. The device is designed for use in embedded applications such as mobile phones, tablets, and other portable electronics. The device features a temperature-compensated precision voltage reference, a programmable current limit, and a thermal shutdown feature. The device is capable of delivering up to 1.5A of output current while consuming a low quiescent current.
