The 80 dB PSRR at 1 kHz is the standout spec here — it attenuates switching ripple from a buck converter by a factor of 10,000, so a 10 mVpp ripple on the input rail becomes roughly 1 µVpp at the output. That matters when you're feeding a 16-bit ADC reference or a low-noise op-amp front-end. Quiescent current is 100 µA — not a micropower part, but acceptable for always-on analog sections where the load current dominates the power budget. ## Package and board-fit — SOT-665 / 5-HVSOF The exposed pad on the bottom side is the thermal path — the datasheet's RthJA assumes a copper land on the PCB under the pad. The Enable pin lets you shut down the output to near-zero quiescent current when the rail is not needed — useful for sequencing or power-saving modes. Protection features include over-current and over-temperature shutdown, so a shorted load on the output won't kill the regulator permanently. ## Lifecycle and compliance — active, ROHS3, no obsolescence watch needed The tape-and-reel packaging (TR suffix) is standard for SOT-665 reels; cut-tape samples are also available for prototyping. Store the reels dry — the MSL level for this package is typically MSL 1 or 2, but confirm the reel label before assuming no bake needed.","metaTitle":"ROHM BH30NB1WHFV-TR LDO, 3V 150mA, 80dB PSRR, SOT-665","metaDescription":"ROHM BH30NB1WHFV-TR linear regulator, 3V fixed output, 150mA, 80dB PSRR at 1kHz.
