It sits in the 8-HTSOP-J package, which pulls heat through the pad into the board copper — a detail that matters when you're laying out the thermal vias under the part. ## Dropout and headroom at 1A Maximum dropout is 0.92V at 1A load. That means the input rail needs at least 2.72V to hold regulation at full current — a 3.3V rail works fine, but a 2.5V rail won't cut it. Quiescent current is 0.6 mA typical, supply current max 900 µA, so the regulator's own draw won't eat into your load budget. ## Active production, ROHS3, and sourcing Status is Active, ROHS3 compliant. ## Thermal and protection features Built-in protection includes over-current, over-temperature, and soft-start. The enable pin lets you sequence the rail or shut it down in standby. Operating temperature range is -25°C to 85°C, covering most indoor and outdoor equipment without needing a wider-range military-grade part.","metaTitle":"BD18GC0WEFJ-E2 1.8V 1A LDO Regulator - ROHM Active","metaDescription":"ROHM BD18GC0WEFJ-E2 fixed 1.8V output, 1A LDO in 8-SOIC exposed pad.

With a 3.3V input and 1.8V output, the dropout is 1.5V — well above the 0.92V max dropout at 1A, so regulation is solid even at full load.
