The BD3987FV-E2 is one of the most popular and reliable Voltage Regulators and Linear PMICs (power management integrated circuits) on the market today. It is a highly advanced, low-noise and low-ripple 3-terminal voltage regulator that provides excellent regulation accuracy and very low power dissipation. It is designed to supply a wide range of voltage output from a wide range of input voltage.

PMICs are applied in various applications including automotive, medical, and consumer electronics. They are used to ensure efficient power conversion and to protect systems from voltage fluctuations, excess current flow, and over-temperature conditions. Linear voltage regulators are one of the most commonly used PMICs in the market today.

The primary application field of the BD3987FV-E2 is in industrial devices, including audio systems, remote control, Bluetooth audio systems, professional video cameras, and power supply of robots. It is also used in instrumentation, satellite communication, and other precision equipment.

The device is capable of supplying a constant voltage output, even under fluctuating or heavily loaded conditions. It provides a high degree of accuracy over a wide range of output voltages of 2.8V–36V. It is designed to operate within a specified temperature range of -30°C–125°C, and also offers low power consumption with current consumption as low as 10µA.

The working principle of the BD3987FV-E2 is based on the DC-DC Buck Converter. It uses electrical energy to convert a DC input voltage of 2.8V–36V to a constant DC output voltage. It is composed of an internal linear voltage regulator, an error amplifier and a driver element. The error amplifier senses the difference between the input and output voltages. When the difference is detected, the error amplifier then adjusts the voltage at the driver terminal, which in turn adjusts the switching element (usually a MOSFET) so as to control the output voltage.

The BD3987FV-E2 is enclosed in a small SOT89-5 or SOT-23-5 package and is ideal for space-constrained applications. It has extensive protection functions, including thermal shutdown circuitry, overcurrent protection, overvoltage protection, and undervoltage protection. It also has a power On/Off switch to enable or disable the regulator.

In conclusion, the BD3987FV-E2 is a highly versatile voltage regulator and PMIC that is used in a variety of applications. It is designed to provide accurate and relatively low power consumption with a wide input voltage range. The device is equipped with a variety of protection functions and is suitable for use in space-constrained applications. The working principle of the device is based on the DC-DC Buck Converter, which uses electrical energy to convert a DC input voltage to a constant DC output voltage.
