Maximum dropout is 0.6V at the full 500mA load — the input must stay at least 0.6V above 1.2V across the load range to maintain regulation. Quiescent current is 0.25 mA typical, with a maximum supply current of 500 µA; the part suits always-on or battery-backed rails where standby draw matters. ## Protection and control for single-rail designs Built-in over-current and over-temperature protection, plus a soft-start feature, cover the common fault modes in a point-of-load regulator. An Enable pin lets the system power down the output — useful for sequencing or sleep-mode power gating. Operating temperature range is -25°C to 85°C, which covers industrial and commercial environments but not extended automotive under-hood duty. No official second-source or pin-compatible cross-reference is carried in the record; the part is single-sourced from ROHM.","metaTitle":"BD12IA5WEFJ-E2 ROHM LDO, 1.2V Fixed, 500mA, 8-HTSOP","metaDescription":"ROHM BD12IA5WEFJ-E2 LDO regulator, 1.2V fixed output, 500mA, 0.6V dropout at full load, 0.25 mA Iq, 8-HTSOP-J.
