The 50 µA quiescent current keeps the regulator's own draw low in always-on ECU or sensor modules, while the 55 dB PSRR at 120 Hz filters 60/100 Hz ripple from a rectified or switched front end — important for analog supply rails feeding an ADC or op-amp. ## Dropout, protection, and temperature range At full 500 mA the dropout is higher but not specified; derate the headroom accordingly. Built-in over-current, over-temperature, and short-circuit protection let the regulator survive a faulted load without external crowbar or fuse — the thermal shutdown cycles the output until the fault clears. ## Package and thermal path The HRP-5 supplier package designation matches the standard D²Pak footprint.","metaTitle":"ROHM BD3571YHFP-MTR LDO Regulator, 5V 500mA, TO-263-6","metaDescription":"ROHM BD3571YHFP-MTR: 5V fixed output LDO, 500mA, 55dB PSRR at 120Hz, 50µA Iq, -40 to 125°C.
