This family of voltage regulator is specifically designed to operate at high levels of efficiency, cost effectiveness and reliability. The BA78M24FP-E2 is capable of providing a highly regulated output voltage from as low as 1.2 V to 24 V.

Application Field

BA78M24FP-E2 is generally used in applications where highly regulated voltage is required for devices operating on low voltage and medium power levels. It can be applied in devices such as digital TVs, digital video recorders, digital audio players, car stereo amplifiers, audio power amplifiers, subwoofers and other high-reliability consumer electronics devices. Because of its high efficiency levels, high reliability, and wide range of operating voltage it is also suitable for automotive applications and medical equipment.

Working Principle

The principle of operation of the BA78M24FP-E2 voltage regulator is based on the concept of a linear series regulator. A linear series regulator consists of a voltage reference, an error amplifier, and a pass element. When power is applied to the regulator, the voltage reference provides a fixed reference voltage for comparison. The error amplifier compares the output voltage with the reference voltage and, depending on the magnitude of the error, turns on or off the pass element accordingly. In this regulator, the pass element is made up of a P-channel MOSFET. When the MOSFET is on, it provides a path between the input and output, allowing current to flow from the input to the output. This process is repeated in a continuous cycle and provides a highly regulated output voltage.

Features

The BA78M24FP-E2 features several features that make it suitable for a wide range of applications. Its output voltage is accurately regulated and it provides excellent ripple rejection. Its low dropout voltage ensures that the device will continue to provide regulation even when the input voltage decreases. The device is also designed to operate under a wide range of temperatures with low thermal resistance, making it suitable for mobile applications. Additionally, its low power consumption and high power savings make it a good choice for battery-powered applications.

Conclusion

The BA78M24FP-E2 is an excellent voltage regulator from Toshiba Semiconductor with capabilities suitable for a wide range of applications. It is capable of providing an accurately regulated output voltage from 1.2 V to 24 V, with excellent ripple rejection, excellent thermal resistance and low power consumption. By combining these features, it is capable of providing highly regulated voltage for many different types of applications.
