The 1.875 V rail is a non-standard voltage — not 1.8 V, not 3.3 V — so it is almost certainly powering a specific core or I/O supply on a mixed-signal ASIC or FPGA that requires that exact level. If the load is a 1.8 V nominal device, check the tolerance; 1.875 V is 75 mV above 1.8 V and may exceed the absolute-maximum rating of a 1.8 V-only pin. ## 3 MHz switching — inductor size and ripple trade-off The 3 MHz switching frequency lets the design use a small-value inductor (typically 1 µH to 2.2 µH) in a 0805 or smaller footprint, which keeps the total solution area tight — important for the 8-DSBGA package that already shrinks the PCB real estate. The trade-off: 3 MHz switching pushes the switching losses up and the efficiency down at light loads compared to a 1 MHz part, but the synchronous rectifier helps recover some of that loss by replacing the freewheeling diode with a low-Rds(on) FET. For a 500 mA load at 1.875 V out, expect efficiency in the mid-80s at full load from a 3.6 V input. ## Input range: 2.7 V min — battery and USB compatibility The 2.7 V minimum input means the part can run from a single Li-ion cell (3.0 V to 4.2 V) down to near its end-of-discharge voltage, or from two alkaline cells in series. The 6 V maximum covers USB bus power (5 V ±10 %) and regulated 5 V rails. If the input is a battery, the 2.7 V undervoltage lockout threshold prevents deep discharge; if the input is a 5 V rail, the 1.875 V output leaves 3.125 V dropout headroom — the buck operates in continuous conduction mode with no dropout concern.","metaTitle":"TPS62305YZDT 500 mA Step-Down Regulator","metaDescription":"Texas Instruments TPS62305YZDT buck regulator: 500 mA output, 2.7 V–6 V input, 3 MHz switching, 8-DSBGA package, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-UFBGA, DSBGA","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Base Product Number":"TPS623","Output Configuration":"Positive","Frequency - Switching":"3MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"-","Supplier Device Package":"8-DSBGA","Voltage - Output (Min/Fixed)":"1.875V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4029e7575af689f25c35ced969df2e40.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62305YZDT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62305YZDT compatible with a 3.3 V input?","answer":"Yes.
