Quality Control: Learn More
Rohm Semiconductor BD3989FV-E2 is a dual output adjustable linear voltage regulator IC. This device provides independent positive and negative voltage regulation with output currents of 25mA and 50mA, respectively. The BD3989FV-E2 features adjustable output voltages ranging from 14V to 16V for the positive rail and -6.5V to -8.5V for the negative rail. It offers a low quiescent current of 0.5mA and a maximum input voltage capability of 18V on the positive side and -7.5V on the negative side. Protection features include overcurrent and overtemperature shutdown. The regulator exhibits a Power Supply Rejection Ratio (PSRR) of 50dB at 120Hz. The BD3989FV-E2 is supplied in an 8-SSOP-B package suitable for surface mounting and finds application in consumer electronics and power management systems requiring dual polarity voltage regulation.
