The 0.9V dropout at full load means the input must stay above 7.9V to maintain regulation — a 12V bus with 5% tolerance clears this with margin. The -25°C to 85°C operating range covers most industrial and telecom ambient conditions, but the junction temperature at 300 mA depends on the PCB copper area under the pad. ## 6 µA quiescent — what that means for always-on loads Quiescent current sits at 6 µA typical, with supply current maxing at 900 µA. For a microcontroller or sensor that spends most of its life in sleep, the regulator's own draw is the floor on standby power — a battery-powered design sees meaningful runtime extension at this Iq level. The Enable and Soft Start control features let the system power up the 7V rail in a controlled ramp, reducing inrush into capacitive loads. Over-current and over-temperature protection are on-die — no external watchdog needed for basic fault handling. ## Active production — sourcing and compliance posture ROHM lists the BD70GA3WEFJ- as Active with RoHS3 compliance.","metaTitle":"ROHM BD70GA3WEFJ-E2 LDO Regulator, 7V Fixed, 300mA","metaDescription":"ROHM BD70GA3WEFJ-E2 linear regulator, 7V fixed output, 300mA, 8-SOIC exposed pad.
