BD3509MUV-E2

The BD3509MUV-E2 is a low-voltage linear voltage regulator, built specifically for applications where power is supplied by either a single cell or dual Li-ion battery. The device can be used as a power supply, a battery charger, or both. The device is ideal for portable electronic devices such as mobile phones, PDAs, handheld game consoles, digital cameras, and other digital devices.

The BD3509MUV-E2 is designed to provide efficient power conversion using its integrated circuit. The main features of the device are its low power consumption, high efficiency and fast start-up time. The device is also designed to provide low-voltage power to the host device, even at very low ambient temperatures.

The basic working principle of the BD3509MUV-E2 is the same as that of other linear voltage regulators. It operates by drawing in a specific input voltage from the battery and then regulating it to a fixed, lower output voltage. The device operates according to the principle of negative feedback, in which a feedback signal is created and compared against a reference voltage. Depending on the differences between the two, an oscillating circuit adjusts the output accordingly. This adjustment is done by either increasing or decreasing the feedback gain, thus increasing or decreasing the output voltage.

The BD3509MUV-E2 is capable of delivering up to 75mA of current at an output voltage of 3V. This is powered by an input voltage of between 2.5V and 20V. The device is suitable for operating at temperatures ranging from -40°C to 85°C.

The BD3509MUV-E2 also has several protection features. These include under-voltage and over-voltage protection, and reverse polarity protection. It also has several other features such as thermal shutdown, over-load protection, and over-current protection. This makes the device ideal for operating in applications that require robust and reliable voltage regulation.

Overall, the BD3509MUV-E2 is an ideal solution for low-voltage applications where power is supplied by either a single-cell or dual Li-ion battery. The device provides high efficiency, low power consumption and fast start-up time. It is also highly reliable, thanks to its robust protection features. This makes it ideal for mobile phones, PDAs, handheld game consoles and other portable digital devices.
