The BD80GA5MEFJ-ME2 is an integrated linear voltage regulator for a variety of applications. This device is part of a complete Power Management IC (PMIC) solution from ROHM Semiconductor that offers a comprehensive portfolio of voltage regulators, voltage references, switching regulators, and other mixed-signal functions. It is a low-dropout (LDO) linear regulator with an input voltage range of 4 V to 6 V, and an adjustable output voltage range of 0.80 to 4.95 V. The output current is specifiied at 0.2 A.

The BD80GA5MEFJ-ME2 is designed to provide reliable and accurate voltage regulation in a variety of applications, including cell phones, Bluetooth headsets, digital still cameras, digital video cameras, and personal computers. It is also well-suited for other applications such as medical equipment, industrial equipment, and military applications.

The device has an input voltage range from 4 V to 6 V, which is sufficient for most applications. The output voltage can be adjusted from 0.80 to 4.95 V in 10 mV increments. The device has a low dropout voltage, typically 0.5 V at 0.2 A, and a high ripple rejection ratio of 60 dB. This ensures that the output voltage remains stable even in the presence of high-frequency noise.

The BD80GA5MEFJ-ME2 also features low quiescent current (consumption when not switching) that is typically < 1 μA at minimum output voltage and < 8 μA at minimum output current. This makes it ideal for battery powered applications that require minimum power dissipation. Furthermore, the device has an operating temperature range of -40℃ to +125℃, making it suitable for extreme environmental conditions. The device also has built-in overcurrent and overvoltage protection, as well as short circuit protection and undervoltage lockout.

The BD80GA5MEFJ-ME2 features simple, single-pin programming of the output voltage. This is achieved by connecting a single external resistor to the chip’s PGM pin. The output voltage is programmed by setting the value of this resistor to desired value. The programming range of the output voltage is from 0.80 to 4.95 V, in 10 mV increments. The PGM pin implies a nominal, internal pull-down current, and the external resistor is used to pull the PGM pin to the desired level.

The BD80GA5MEFJ-ME2 is a versatile, low-cost, low-power LDO regulator with an impressive list of features. With an adjustable output voltage range of 0.80 to 4.95 V, a low dropout voltage, excellent efficiency and low quiescent current, the device is suitable for a wide range of applications from consumer electronics to industrial and military applications. The simple, single-pin programming of the output voltage makes it easy to use, cost-effective, and requires minimal external components.
