BA178M05FP-E2

Voltage Regulators - Linear

The BA178M05FP-E2 is an integrated, low supply voltage, low dropout (LDO) linear regulator, designed for a wide range of applications. It is available in surface mount P-DSO-8 package, and is ideal for applications where small size, high performance, and low power consumption are required. The regulator features low quiescent current and low noise, making it suitable for many low power designs. It is designed with internal protection features including reverse current protection, over current protection, over temperature protection, and over voltage protection.

Application Field

The BA178M05FP-E2 is suitable for a wide range of applications where the regulated output voltage is regulated to the reference voltage. It is widely used in embedded systems, audio/video applications, cellular phones, digital set-top boxes, and computer applications. The device is also suitable for use in all kinds of portable devices, especially in battery operated ones, as it has low dropout and low quiescent current characteristics, making it suitable for low power applications.

Working Principle

The BA178M05FP-E2 regulator works on the principle of a feedback loop. It is a feedback control system consisting of an Operational Amplifier (Op-Amp) and an error amplifier. The error amplifier compares the output voltage of the regulator to the internal reference voltage, and generates a signal, which is applied to the Op-Amp. The Op-Amp amplifies the error signal to drive an output transistor, which in turn controls the output voltage of the regulator. In order to achieve power conservation, the regulator operates with the minimum possible output current, and therefore the output voltage is lower than the reference voltage.

Conclusion

The BA178M05FP-E2 is an integrated, low supply voltage, low dropout linear regulator. It is suitable for low power applications, and features internal protection features including reverse current protection, over current protection, over temperature protection, and over voltage protection. It is designed for a wide range of applications and is typically used in embedded systems, audio/video applications, cellular phones, digital set-top boxes, and computer applications.
