BA07CC0FP-E2 Application Field and Working Principle

BA07CC0FP-E2 stands for a 78L05 linear Voltage Regulator PMIC (Power Management Integrated Circuit). This PMIC belongs to the class of Regulators that are designed to provide a stable voltage supply, constant current and heat based protection across a wide variety of applications. A Voltage Regulator is an electronic device which controls the output voltage of an output unit or device, to maintain a consistent energy supply.

Application Field

The BA07CC0FP-E2 provides regulation with low output voltage and low dropout. An example of its application is the supply of the main power for small logic circuits. It can also provide constant power for 12V, 15V and 18V logic circuits and circuits with a common ground. This device is also suitable for semiconductor laser drivers, cameras, mobile phones, and other small and medium-sized electronic products.

Working Principle

Linear Voltage Regulators are composed of three parts; the control circuitry, the voltage reference and the pass element. The first part, the control circuit, monitors the voltage at the output and compares it to the reference voltage. When the actual output voltage exceeds or is less than the reference voltage, it activates the pass element which then reduces or increases the amount of current flowing through the output. As a result, the output voltage is regulated according to the reference voltage.

The BA07CC0FP-E2 is an integrated voltage regulator which has a voltage regulator circuit and a logic controller built into one package. Because of the low quiescent current, it is usually used as an on-chip main power supply. The integrated voltage regulator consists of two parts; a discrete transistor and an integrated voltage reference. The discrete transistor acts as the pass element while the integrated voltage reference controls the maximum output of the regulator.

The BA07CC0FP-E2 has a voltage range of 2.5 V to 18 V, with a default voltage of 5 V. In its linear operating mode, the regulator features low dropout, low power consumption and low noise. It also has a high operational stability and an over-current protection. This feature helps to protect its sensitive logic components in the case of overload or short-circuit.

Conclusion

The BA07CC0FP-E2 is an integrated voltage regulator which provides a low voltage, low power consumption and low noise output. It provides a stable voltage supply and constant current for a wide range of applications,such as for semiconductor laser drivers, cameras, mobile phones and other small and medium-sized electronic products. It features low dropout, low power consumption, low noise and high operational stability as well as an over-current protection feature to protect its logic components in the event of overload or short-circuit.
