BA178M15T is a ground-reference, three-terminal, low-dropout linear regulator. It features low quiescent current and high-current throughput, making it well-suited to a broad range of portable applications. The output voltage is adjustable from 1.2 to 5.0 volts and delivers up to 1.5 amps of output current.

The BA178M15T linear regulator is a three-terminal device with an internally-generated reference voltage. Its input voltage can range from 2.3V to 6V, and its output voltage is adjustable from 1.2V to 5V. It is a fixed-frequency, non-synchronous device featuring low quiescent current and high-current throughput. Its wide input voltage range and low dropout voltage make it ideal for portable applications that require a low-voltage regulator with high current capability.

The BA178M15T works by regulating the output voltage through an internal voltage reference and an error amplifier. The quiescent current of the regulator is determined by the difference between the input and reference voltages. In normal operation, the dropout voltage of the BA178M15T is typically 180mV at 1A. Depending on the application, the dropout voltage can range from 140mV to 180mV.

A key feature of the BA178M15T is its ability to start up from a lower voltage without needing a large external capacitor. This feature makes the BA178M15T ideal for use in a wide range of applications. It can be used to power low-voltage 3.3V logic and 12V systems, and also in solar, vehicle, and industrial applications. The device also offers over-temperature, inrush current, and line transient protection.

The BA178M15T is a reliable and highly efficient linear regulator. Its stability is determined by the internal error amplifier, the compensation network, and the output voltage feedback loop. Its output will not oscillate at any load current, and the device can also be over-loaded without damage.

The BA178M15T is suitable for a wide range of applications, particularly in portable and automotive applications. Its wide input voltage range, low dropout voltage, and high-current throughput make this device an ideal solution for applications that require a low-voltage, high-current regulator.
