AP431AQL-7

Introduction to AP431AQL-7

AP431AQL-7 is a 3-terminal, adjustable and high-accuracy voltage reference, designed to provide an output voltage of 0.8 to 7V. It is part of the PMIC – Voltage Reference family, making it suitable for a wide range of applications. The device has an input voltage of ±3 V, allowing it to function over a wide voltage range, and it offers a load regulation of 0.01 %/V. The output voltage of the device is adjustable via a single external resistor, and can be set to a wide range of voltages, depending on the resistance value of this resistor. Other features, such as a maximum 6uA current consumption, and a maximum temperature rise of 15 °C, make it ideal for use in a variety of applications.

Output Voltage Calibration

The output voltage of the AP431AQL-7 can be adjusted by the use of an external resistor, with a minimum resistance of 1 KΩ and a maximum resistance of 10 KΩ. When a resistor of 10 KΩ is used, the output voltage is set to the minimum (0.8 V), and as the resistance of this resistor is decreased, the output voltage increases proportionally, up to a maximum of 7 V. Once the desired output voltage is selected, it is accurate to 2%.

AP431AQL-7 operating temperature and features

The AP431AQL-7 is designed to operate within a temperature range of -40°C to +85°C, meaning it is well suited to a variety of applications, including those which require a device to operate in extreme temperatures. It also features a maximum power dissipation of 850 mW, and a maximum 6uA quiescent current, meaning it can be used in low power applications. Furthermore, the device offers maximum temperature rise of 15°C, which is important for applications which require devices to not exceed certain temperature thresholds.

Applications of AP431AQL-7

The wide range of features offered by the AP431AQL-7 make it ideal for use in a variety of applications, including precision voltage monitoring, power supply voltage pre-regulating, and as a reference voltage for other circuit devices such as comparators and DACs. The low power construction of the device also ensures it is well suited for use in portable devices such as laptops, tablets and mobile phones. Other applications include medical imaging equipment and industrial machinery.
