It is built for surface-mount assembly in the TO-252-5 (DPak) package, with the tab providing a thermal path to the board. The 55 dB PSRR at 120 Hz tells you this part handles rectified-ripple rejection from a mains-derived supply — useful when the input comes from a bulk capacitor after a bridge rectifier or a flyback converter running at line frequency. The quiescent current sits at 0.5 mA, which keeps the standing loss low in always-on rails. ## Industrial temperature and protection — where this part lives The over-current and over-temperature protection are built in — no external watchdog needed for basic fault survival. Maximum input voltage is 16 V, so it tolerates a 12 V nominal rail with headroom for transients. ## Enable pin — sequencing without extra logic The control feature is an enable pin, letting you sequence this rail on and off with a logic signal. That saves a discrete load switch or a supervisor IC when the system needs a delayed power-up or a shutdown sequence for a microcontroller or analog front end. ## Package and rework — TO-252-5 with tab The TO-252-5 (DPak) has four leads plus a tab. The tab is the main thermal path — a good via stitch under it keeps the junction temperature under control at 1 A continuous.","metaTitle":"ROHM BA33BC0WFP-E2 LDO Regulator, 3.3V Fixed Output, 1A","metaDescription":"ROHM BA33BC0WFP-E2 LDO voltage regulator: fixed 3.3V output, 1A, 55dB PSRR at 120Hz, -40°C to 105°C, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"PSRR":"55dB (120Hz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-252-5, DPak (4 Leads + Tab), TO-252AD","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"1A","Protection Features":"Over Current, Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 105°C","Voltage - Input (Max)":"16V","Current - Supply (Max)":"900 µA","Supplier Device Package":"TO-252-5","Current - Quiescent (Iq)":"0.5 mA","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.68","priceTiers":[{"qty":1,"price":"$1.68000","currency":"USD"},{"qty":10,"price":"$1.49800","currency":"USD"},{"qty":25,"price":"$1.42160","currency":"USD"},{"qty":100,"price":"$1.16780","currency":"USD"},{"qty":250,"price":"$1.09164","currency":"USD"},{"qty":500,"price":"$0.96470","currency":"USD"},{"qty":1000,"price":"$0.76161","currency":"USD"},{"qty":2000,"price":"$0.71850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8fee7db6c7fdd8e9385256a0983f91af.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BA33BC0WFP-E2/alternatives.json"},"ai":{"faq":[{"question":"Does BA33BC0WFP- have an enable pin?","answer":"Yes, the BA33BC0WFP- includes an enable control feature, allowing the output to be turned on and off with a logic-level signal."},{"question":"What is the PSRR of BA33BC0WFP-?","answer":"The power supply rejection ratio is 55 dB at 120 Hz, which is the line-frequency ripple rejection figure relevant for mains-derived inputs."},{"question":"What is the difference between BA33BC0WFP- and BA33BC0WFP?","answer":"The - suffix typically indicates a tape-and-reel packaging option for automated assembly.
