Quiescent current is 1.2 mA typical — modest for a 300 mA LDO, but worth budgeting in battery-powered designs where the regulator's own draw competes with the load during sleep states. ## Protection and control — what is on-chip Built-in protection covers over-current, over-temperature, and short-circuit events — the regulator shuts down and auto-recovers when the fault clears. An enable pin allows the output to be gated by a logic signal, and a soft-start circuit limits inrush current during power-up.","metaTitle":"ROHM BD33HA3MEFJ-LBH2 LDO, 300 mA, 3.3 V Fixed, 8-SOIC","metaDescription":"ROHM BD33HA3MEFJ-LBH2 LDO regulator, 300 mA fixed 3.3 V output, 1.2 V dropout max, -40 to 105°C, 8-HTSOP-J.
