BA09FP-E2

PMIC - Voltage Regulators - Linear

A voltage regulator is a key component of any electronic circuit or system. They are used to convert a voltage from one level to another, or to maintain a constant output voltage level.

One of such devices is the BA09FP-E2 Linear Voltage Regulator, which is commonly used in various electrical systems like in home electronics, automotive and industrial applications.

Application Field

The BA09FP-E2 is used as a linear voltage regulator in a variety of applications. It is small, light and cost effective with a high current range of up to 1A. It is suitable for most .8V to 9V applications and is ideal for nominal 9V operations. It can also be used for voltages up to 20V and can be operated with a maximum output current of up to 1.5A.

The BA09FP-E2 is frequently used in systems ranging from home electronics to automotive and industrial applications. Its low cost, high current range and small size make it an ideal choice for many applications.

Many home electronics and automotive systems can benefit from the BA09FP-E2. It can be used to regulate the output voltages of battery and DC power supplies, as well as air conditioners, refrigerators and wind turbines. For example, in cars, the BA09FP-E2 can function as a voltage regulator to prevent the battery voltage from dropping too low. It is also used in electrical power supplies, medical devices and measurement instruments.

Working Principle

The BA09FP-E2’s working principle is based on the use of a feedback loop. This feedback loop ensures output voltage stability by constantly monitoring and adjusting for any significant voltage changes. The device is designed with an input voltage range of 1.8V to 8V and with an output voltage range of .8V to 9V.

The BA09FP-E2 is made up of two components: the rectifying diode and the transistor. The rectifying diode rectifies the input AC voltage to a DC voltage of 1.8 to 8 volts. This voltage is then passed on to the transistor, which acts as a voltage boost and converts the rectified DC voltage to the output voltage of .8 to 9 volts.

The transistor also contains an error amplifier, which senses the difference between the rectified output voltage and the desired output voltage and adjusts the transistor\'s output accordingly. This feedback loop helps to maintain a stable output voltage, even when there are sudden voltage fluctuations.

The BA09FP-E2 also has protection features such as reverse polarity, short-circuit, over-voltage, thermal overload and over-current protection. These protections ensure the safety of the regulator and the device it is connected to.

Conclusion

The BA09FP-E2 is a powerful and cost-effective voltage regulator that can be used in a variety of applications. Its small size and low cost make it an ideal choice for many home electronics, automotive and industrial applications. Its reliable and accurate output regulation, combined with its built-in protection circuitry, make the BA09FP-E2 an excellent choice for many applications.
