Working Principle

The MIC5504-1.2YM5-TR is a linear voltage regulator that is designed to provide a constant output voltage via an internal P-channel MOSFET. The voltage regulator operates by dissipating the excess current from the output when the current draw of the load exceeds the load limit of the regulator. The MOSFET is controlled by the controller IC that reduces the output voltage when the load current exceeds the load limit. The IC also provides protection from short-circuits, thermal shutdown and overload. The device operates in a fixed frequency and with a low quiescent current, making it an ideal solution for battery-powered applications.

The MIC5504-1.2YM5-TR also features adjustable switching frequency. This enables the user to optimize the efficiency of the regulator based on the application. The device also features an output voltage monitor that helps monitor the output voltage versus input voltage. The MIC5504-1.2YM5-TR is designed to provide reliable and accurate regulation with minimal noise and low-ripple output.

The MIC5504-1.2YM5-TR is a highly integrated and cost-effective linear voltage regulator that is ideal for applications where size and cost are critical. It is suitable for low voltage, high current applications such as portable gaming, cellular phones, digital cameras and portable navigation systems.
