PMIC - Voltage Regulators - Linear

Voltage regulators are important components in a variety of power management systems and applications. Linear regulators provide a simple, efficient, and inexpensive solution to stabilize a voltage. BDJ2GA3WEFJ-E2 is a linear voltage regulator from Mitsubishi Electric. This article discusses the application fields and working principle of this device.

Introduction to Linear Regulators

Linear voltage regulators are designed to take a higher voltage input and reduce the output voltage to lower, stable values. This is useful for applications where a fixed, regulated voltage is desired for optimal operation of the circuit.

The BDJ2GA3WEFJ-E2 is a three-terminal regulator in the industry standard TO-220 package. When used in a linear regulation circuit, it provides output voltage regulation over a wide input voltage range. The device has an output voltage accuracy of ±2% and a power dissipation of 10 W.

Applications

The BDJ2GA3WEFJ-E2 is ideal for a variety of applications. It can be used for voltage regulation, voltage stabilization, and ripple reduction in consumer and industrial electronic circuits, such as microcontrollers, AC/DC converters, power supplies, and battery chargers. The device can also be used in automotive, aerospace, and medical applications.

Working Principle

The BDJ2GA3WEFJ-E2 is an N-channel, series-mode, three-pin voltage regulator. It operates in linear-mode and provides a regulated voltage output and current limiting. The device works by comparing the output voltage to an internal reference voltage. When the output voltage drops below the reference voltage, the regulator turns on an internal power transistor, which supplies current to the output. When the output voltage rises above the internal reference voltage, the regulator turns off the power transistor.

The BDJ2GA3WEFJ-E2 features a wide input voltage range, over-current protection, and thermal protection. It is designed to maintain a steady output voltage when the input voltage changes or load current varies. The device also features a low standby current, which reduces power consumption when the regulator is not being used.

Conclusion

The BDJ2GA3WEFJ-E2 is a linear voltage regulator from Mitsubishi Electric. It is designed to provide regulated output voltage over a wide input voltage range. The device is well-suited for a variety of applications, including microcontrollers, AC/DC converters, power supplies, and battery chargers. The device operates by comparing the output voltage to an internal reference voltage and turning on or off an internal power transistor based on the comparison. It is designed to provide reliable power regulation in a variety of conditions.
