AN8025 Application Field and Working Principle

AN8025 is a high-performance and low-cost low-dropout (LDO) linear voltage regulator from Panasonic. It is suitable for a wide range of applications from analog and digital circuit power supplies to various power converters. The AN8025 is widely used in PMIC applications, especially in the field of Voltage Regulators. It is an ideal solution for providing accurate and reliable power supply to critical circuit blocks in next-generation integrated circuits.

The AN8025 is a linear voltage regulator, which is designed to provide a stable output voltage in the presence of varying input voltages and load variations. This voltage regulator features a low output voltage drop, high power efficiency and low power dissipation, making it a suitable choice for supplying a wide range of applications. It also provides excellent temperature stability, which makes it ideal for applications which requires high reliability and robustness. The AN8025 is available in two different versions – the 8-pin and 20-pin versions.

The working principle of the AN8025 is quite simple. It is a three-terminal integrated circuit that uses a combination of resistors, capacitors, and transistors to regulate and control the output voltage. The resistors and capacitors form a series of voltage dividers and filters which means that there are different sets of resistors and capacitors for each different output voltage. The voltage regulator then adjusts the output voltage by changing the resistance of the resistors and the capacity of the capacitors accordingly, so that a constant output voltage is maintained despite input voltage and load variations.

The output voltage of the AN8025 is adjustable in a range between 1.5V to 12V. It has an adjustable output current ranging from 1A to 3A. The output voltage is set with two external resistors. This is extremely useful in applications where the exact voltage is required and allows the user to fine-tune the output for optimal performance. The AN8025 also provides excellent current limiting, which allows it to protect the circuit in case of a high current load. The output voltage of the AN8025 can also be adjusted digitally with a DAC output.

The AN8025 is a reliable and cost-effective solution for various voltage regulation applications. The wide range of output voltage, adjustable output current, and digital control make the AN8025 an ideal choice for a variety of applications ranging from consumer electronics, telecommunication, and industrial systems.
