REG102GA-A

PMIC - Voltage Regulators - Linear

Voltage regulators are electronic devices used to provide a stable or regulated output voltage. Linear voltage regulators are among the most popular types of regulators because they are relatively simple, inexpensive, and highly reliable. This article discusses one type of linear voltage regulator – the REG102GA-A.

Applications

The REG102GA-A is a low-dropout, linear voltage regulator designed for mobile applications. It is capable of providing an output voltage of 1.8 V to 5.5 V with a maximum current of 800 mA. It is suitable for powering mobile device peripherals, such as displays, audio, Wi-Fi and memory controllers.

Working Principle

The REG102GA-A is designed for low current and low voltage applications. It consists of two primary components, an adjustable regulator and a power amplifier. The adjustable regulator works by dropping a small amount of voltage from the input to the output, thus providing a regulated output voltage. The power amplifier amplifies the output signal, allowing it to reach the desired voltage level. The device also includes built-in protection circuitry to ensure safe and reliable operation in environments with potentially unstable power supply.

Advantages

The REG102GA-A is a versatile and cost-effective solution for mobile devices. It is easy to integrate, requires minimal external components, and consumes low amounts of power. Its built-in protection circuitry ensures safe operation and reliability in harsh environments. Additionally, its output voltage can be easily adjusted with a single external resistor, making it suitable for a variety of applications.

Conclusion

The REG102GA-A is a linear voltage regulator designed for mobile applications. It can provide multiple adjustable output voltages, and its built-in protection circuitry ensures reliable operation in uncertain environments. It is an ideal solution for powering peripherals such as displays, audio, Wi-Fi and memory controllers.
