Application Field

The MIC5281-5.0YMM-TR is a low-cost, low-power voltage regulator that can be used in a variety of applications, including industrial and automotive. It is particularly well suited for small, portable electronics, such as portable media players, digital cameras and mobile phones. It is also suitable for use in power management systems, providing current and voltage regulation from battery sources such as lead-acid and nickel cadmium. The device is designed to provide drop-in replacement capability in existing circuitry, eliminating the need for costly redesigns.

Working Principle

The MIC5281-5.0YMM-TR voltage regulator operates on a linear regulation principle. In linear regulation, a constant input voltage is compared with a reference voltage, and the difference between the two signals is converted into current, which is then used to control the output voltage. The device has a wide input supply range of +2.7V to +20V and its output voltage range is adjustable from its full-line minimum to its full-line maximum. The output voltage is also trimmed to its desired value by the voltage options. The device can provide up to 150mA of current, and is also equipped with over-current and thermal protection.

The MIC5281-5.0YMM-TR features an ultra-low quiescent current of 250uA. This is important in modern, high-speed digital circuits, as it reduces power consumption while maintaining a stable output voltage. Additionally, the device has fast transient response capabilities, and can handle highly dynamic loads due to its low output impedance. The device also provides low EMI, allowing it to be used in noise sensitive applications such as medical and automotive.

The MIC5281-5.0YMM-TR is a versatile, low-cost voltage regulator with many features that make it suitable for a wide range of applications. It is particularly well suited for small, portable electronics, as it is capable of providing up to 150mA of current, as well as thermal and over-current protection. Additionally, the device\'s low quiescent current, fast transient response and low EMI make it well suited for noise sensitive applications.
