BA78M15FP-E2 is a linear voltage regulator integrated circuit (IC) that belongs to the Low Dropout (LDO) regulator family. It is designed to provide a regulated voltage output for variable input voltage, from +400mV to +1800mV, with maximum instantaneous output current up to 250mA. It is typically used in battery-powered systems, such as mobile phones, PDAs, digital cameras, portable media players, laptop computers, and other electronic devices.

The BA78M15FP-E2 combines an ultra-low dropout voltage regulator with a low dropout voltage reference into a single-channel, monolithic chip. The chip includes an enable pin, allowing the device to be shut down to a very low quiescent current draw. It is also equipped with over-current, thermal-shutdown and over-voltage protection.

Operationally speaking, the BA78M15FP-E2 has an internal reference voltage of 0.9V, an enable pin that can be used to shut down the device, and an output voltage that is adjustable from 0.4V to 1.8V. The output voltage is determined by the ratio between a series resistor connected between the output and the adjust pin (R1) and a parallel feedback resistor connected between the adjust pin and ground (R2). The output voltage can be adjusted by varying R1 and R2.

The BA78M15FP-E2 is a very efficient and reliable linear voltage regulator. With its low dropout, wide input voltage range and 250mA maximum output current, it is ideal for applications such as mobile phones, PDAs, digital cameras, portable media players and laptop computers.

In addition to its application in battery-powered systems, the BA78M15FP-E2 can also be used as a general purpose linear voltage regulator in other electronic circuits. Its excellent performance, low cost and high reliability make it an ideal choice for a variety of applications.
