BD7xxL05G-C Series Compact Primary LDOs

ROHM's BD7xxL05G-C series meets basic requirements, such as compact size, support for +125°C (ambient temperature) operation, qualification under the AEC-Q100 automotive reliability standard, and low current consumption demanded of automotive redundant power supplies. Moreover, they can be used as primary power supplies (45 V rated input voltage) despite their small size, with a lineup that makes it possible to select the ideal solution according to the downstream device (i.e., sensor, MCU).

These LDOs are also highly resistant to disturbance noise, suppressing output voltage fluctuations to less than 50 mV (<±1%) over the entire frequency band under ISO 11452-2 antenna irradiation testing, reducing the number of work hours required for noise countermeasures.
