PMIC - Voltage Regulators - Linear

The AP7361-FGE-7 voltage regulator is a linear regulator from Diodes Incorporated, a leading provider of semiconductor products. It is an integrated, low-power, positive adjustable, high-voltage solution for a wide range of microcontrollers, processors, and analog sensors. The AP7361-FGE-7 provides a low-noise, high-performance solution for applications requiring low-power consumption, such as cell phones, PDAs, and other portable devices.

Application Field

The AP7361-FGE-7 voltage regulator is designed for use in a variety of applications. It is suitable for a wide range of microcontrollers and processors, including the following: Atmel, NXP, STMicroelectronics; TI, Microchip Technology, and many others. The regulator is also suitable for analog sensors, including Hall Effect, wind speed, and many others. The AP7361-FGE-7 offers a low-voltage solution with an adjustable output voltage range of 0.8V to 3.3V with a max load current of 1A.

Working Principle

The AP7361-FGE-7 linear regulator is based on the Buck-Boost (Bunkiewicz) converter topology. This topology utilizes an inductor-capacitor (LC) voltage division network to reduce the required components and provide efficient regulation in a small footprint. The current flow between the input and output is regulated by an internal error amplifier, which controls the voltage across an output stage. It supplies current to the load and adjusts the voltage on the output terminal in response to analog input signals. In addition, the AP7361-FGE-7 features a low quiescent current, low-dropout design and high transient response, which makes it suitable for applications with high dynamic loads. The regulator operates up to 3.3V and has an adjustable output voltage range from 0.8V to 3.3V.

Protection

The AP7361-FGE-7 voltage regulator provides protection from overload and over Voltage (UVLO). It includes an internal temperature sensor that senses the temperature of the chip and stops the operation if the temperature rises above a preset limit. The package also includes an active-low version of the reset signal (RO), which offers additional protection against overvoltages and prolonged overloads due to external fault conditions. Finally, the regulator also features an active-low power-good indicator (PGO) pin, which provides an indication that the output voltage is within the regulation range.

Conclusion

The AP7361-FGE-7 voltage regulator from Diodes Incorporated is an integrated, low-power solution for supplying regulated power to a variety of microcontrollers, processors, and analog sensors. It offers a low-noise and high-performance solution with an adjustable output voltage range from 0.8V to 3.3V, and a max load current of 1A. The regulator is also protected from overload and overvoltage conditions and includes a power-good indicator. As such, it is suitable for a wide range of applications requiring low-power consumption, including cell phones, PDAs, and other portable devices.
