PMIC - Voltage Regulators - Linear

Voltage regulators are one of the most important components in the field of power management. One key type of voltage regulators are linear regulators, which are used to provide a stable output voltage from an unregulated voltage source. The REG101UA-2.5/2K5, from RECOM, is an example of a linear regulator. This article will discuss its application field and working principle.

Applications

The REG101UA-2.5/2K5 is a low-dropout (LDO) linear voltage regulator, meaning that it can provide a stable output voltage with a very low voltage drop. It is suited for a variety of applications, including portable and battery-powered devices, as well as applications that require a low input voltage, such as automotive systems.The REG101UA-2.5/2K5 is a low-noise device that is designed to reduce the noise generated by switching power supplies or other noisy circuits, making it well-suited for audio and instrumentation applications. It also has an incredibly low quiescent current, making it extremely energy efficient for low-power applications.

Working Principle

The REG101UA-2.5/2K5 is a linear regulator, which means that it uses a voltage regulator circuit to adjust its output voltage. This circuit consists of a negative feedback loop, which uses a feedback signal to constantly adjust the output voltage to match the required setpoint.The key to the working principle of the REG101UA-2.5/2K5 is its low-dropout design. This design allows the regulator to maintain a stable output voltage even when the input voltage is very close to the output voltage. This is achieved by using a pass transistor, which is responsible for transferring power from the input voltage to the output.

Conclusion

The REG101UA-2.5/2K5 is a low-dropout linear voltage regulator, which is well-suited for a variety of applications, from portable devices to automotive systems. It is optimized for low-noise and low-power applications, as well as for energy efficiency. Its working principle is based on a negative feedback loop and a low-dropout pass transistor.
