Product details

300 mA fixed 3.3 V LDO — headroom and dropout

The BD33HA3MEFJ-LBH2 is a positive fixed-output LDO from ROHM, delivering 300 mA at 3.3 V. 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.
