Output is fixed at 5 V with 500 mA continuous current — enough to power a CAN transceiver, a small MCU, or a sensor bias rail in an ECU. Dropout voltage is 0.5 V maximum at 200 mA load; the input-to-output differential must stay above this to maintain regulation. ## Quiescent current and PSRR for noise-sensitive rails Quiescent current is 6 µA typical, keeping the regulator's own draw low for always-on modules in battery-backed ECUs. Power supply rejection ratio is 60 dB at 120 Hz — typical for a linear regulator; it attenuates 120 Hz ripple from a full-wave rectifier by 1000×, but at higher frequencies the rejection rolls off, so switching noise upstream should be filtered ahead of the LDO. ## Protection and package Over-current and over-temperature protection are built in — the part shuts down on a hard short or thermal runaway, reducing the risk of a cascading failure on the board. ROHS3 compliant — no restricted substances in the bill of materials; PPAP documentation and AEC-Q qualification reports are available from the manufacturer.","metaTitle":"ROHM BD750L5FP-CE2 LDO, 5V Fixed, 500mA, AEC-Q100, TO-252","metaDescription":"ROHM BD750L5FP-CE2 automotive LDO: 5V fixed output, 500mA, 45V max input, 60dB PSRR at 120Hz, AEC-Q100 qualified.
