Housed in a TO-220-5 Full Pack (TO-220FP-5) through-hole package, it suits designs where the tab needs electrical isolation from the heatsink without an insulating pad. The 0.7V maximum dropout at 2A means the input must stay above 3.7V to maintain regulation at full load — a 5V rail provides 1.3V of headroom, adequate for most post-regulation stages. ## Protection and control for reliable supply rails Built-in protection covers over-current, over-temperature, and over-voltage conditions — the regulator shuts down before the load or the pass element sees damage from a fault on the input or output side. An enable pin lets the system designer gate the output on and off, useful for sequencing multiple rails or reducing quiescent draw in a sleep state. Quiescent current sits at 120 µA typical — low enough for always-on auxiliary rails in industrial control or automotive body electronics where the regulator stays powered during key-off. ## PSRR and temperature range for analog loads Power supply rejection ratio is 55 dB at 120 Hz — this attenuates the 100/120 Hz ripple from a full-wave rectified bulk supply by a factor of about 560, cleaning the rail for sensitive analog front-ends. RoHS3 compliant per the manufacturer's declaration, with no exemptions that would restrict EU or global market use.","metaTitle":"BA30DD0WT ROHM LDO Regulator, 3V Fixed, 2A, TO-220-5","metaDescription":"BA30DD0WT from ROHM Semiconductor: 3V fixed-output LDO, 2A, 0.7V dropout at full load, 55dB PSRR at 120Hz.
