Its 50 dB PSRR at 120 Hz means it knocks down mains-frequency ripple by a factor of about 316 — relevant if you are feeding a clean analog rail from a switching preregulator or a lightly filtered 5 V bus. ## Output range and dropout — where the headroom lives Output is adjustable from 1 V up to 4 V via an external resistor divider. The maximum dropout is 0.2 V at 200 mA. Quiescent current maxes at 550 µA, and the part includes enable control plus over-current and over-temperature protection.","metaTitle":"ROHM BD00KA5WF-E2 LDO Regulator, Adjustable 500 mA, 8-SOIC","metaDescription":"ROHM BD00KA5WF-E2 adjustable LDO regulator: 500 mA output, 50 dB PSRR at 120 Hz, 0.2 V dropout at 200 mA, -40°C to 105°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"PSRR":"50dB (120Hz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"500mA","Protection Features":"Over Current, Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 105°C","Voltage - Input (Max)":"5.5V","Voltage Dropout (Max)":"0.2V @ 200mA","Current - Supply (Max)":"550 µA","Voltage - Output (Max)":"4V","Supplier Device Package":"8-SOP","Current - Quiescent (Iq)":"550 µA","Voltage - Output (Min/Fixed)":"1V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.69","priceTiers":[{"qty":1,"price":"$1.69000","currency":"USD"},{"qty":10,"price":"$1.50700","currency":"USD"},{"qty":25,"price":"$1.43040","currency":"USD"},{"qty":100,"price":"$1.17510","currency":"USD"},{"qty":250,"price":"$1.09848","currency":"USD"},{"qty":500,"price":"$0.97074","currency":"USD"},{"qty":1000,"price":"$0.76638","currency":"USD"},{"qty":2500,"price":"$0.72300","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fd222b4d7dc7ba27de9dc2c0d168b2ad.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BD00KA5WF-E2/alternatives.json"},"ai":{"faq":[{"question":"What is a suitable replacement for BD00KA5WF-?","answer":"The ROHM BA33BC0WFP- is a fixed 3.3 V output LDO with 55 dB PSRR at 120 Hz and 1 A output, but it is not a direct adjustable replacement — the BD00KA5WF-'s adjustable output from 1 V to 4 V covers a wider set of rail voltages.
