Output range and dropout budget
The BD00HA3MEFJ-LBH2: Adjustable output from 1.5 V minimum up to 7 V maximum, delivering 300 mA continuous. The max dropout is 1.2 V at full load — the input rail must stay at least 1.2 V above the set output voltage across the load range to hold regulation. Single positive regulator with Enable control — the Enable pin lets a logic-level signal gate the output without a separate pass FET.
Protection and temperature grade
Built-in Over Current, Over Temperature, and Soft Start protection — the soft start limits inrush into bulk capacitance on power-up, preventing output overshoot and input rail sag.
8-HTSOP-J package (0.154" SOIC-8 width, 3.90 mm body, exposed pad).
Lifecycle and compliance
Maximum supply current is 1.2 mA — the regulator's own quiescent draw is low enough for always-on rails in battery-backed systems.
