The BD25IC0MEFJ-LBH2 is a linear voltage regulator from the Power Management Integrated Circuit (PMIC) series. It is a voltage regulator that is specifically designed with a low device saturation voltage. It is suitable for use in applications where a low-cost integrated circuit with a wide voltage range is required. Additionally, it is suited for use in notebook computers and consumer electronics.

The BD25IC0MEFJ-LBH2 is composed of five main sections: input capacitance, voltage regulator, output capacitance, reference voltage generator and protection circuitry. The input capacitance is designed to reduce the amount of high-frequency ripple present on the input power line. The voltage regulator controls the output voltage by connecting it between the input voltage and ground. The output capacitance helps reduce the output voltage ripple and improve the output voltage stability. The reference voltage generator provides a precise output voltage across the entire input voltage range. Lastly, the protection circuitry adds protection against overvoltage, overcurrent, and output short circuit conditions.

The core of the BD25IC0MEFJ-LBH2 is the internal voltage regulator which works in two modes. The voltage regulation mode is activated by an external open-drain output (DRV). The DRV signal eliminates any reverse current through the voltage regulator and ensures that the output voltage remains stable even when the load current is drawing large amounts of current. The power-saving mode is activated when the DRV is low and enables the voltage regulator to reduce quiescent current consumption.

The BD25IC0MEFJ-LBH2 offers a wide range of output voltage options. The output voltage range is between 5V and 12V with a maximum output current of 700 mA in voltage regulation mode and up to 1A when using the power-saving mode. The BD25IC0MEFJ-LBH2 also includes built-in overvoltage, overcurrent, and output short circuit protection circuits to ensure the device is not damaged due to external conditions. Additionally, the device includes low-dropout performance for battery powered systems.

The BD25IC0MEFJ-LBH2 is a low-cost linear voltage regulator specifically designed for use in a wide range of applications from notebooks to consumer electronics. It offers a wide selection of output voltage options, along with overvoltage, overcurrent, and output short circuit protection circuits to ensure the device’s operation is not impacted by external conditions. Additionally, the built-in power-saving mode reduces quiescent current consumption and ensures the device operates at optimal efficiencies when in operation.
