The boost output delivers a regulated 3.3V at up to 1.8A, while the LDO provides a second adjustable rail from 0.9V to 3.6V at 500mA — enough for a small sensor node or portable instrument needing two supply voltages from one battery. ## Boost rail: 3.3V at 1.8A, synchronous rectification ## LDO rail: adjustable 0.9V to 3.6V at 500mA The second output is a linear regulator with an adjustable output from 0.9V up to 3.6V. At 500mA it provides a clean, low-noise rail for analog or RF sections where the boost converter's ripple would be problematic. The LDO's input is taken from the boost output, so both rails share the same battery source. ## Obsolete — plan for a replacement now Confirm BOM fit and quantity before committing; the 24-VQFN footprint may be shared with other TI power devices in the same package, but pin compatibility should be verified against the target application.","metaTitle":"TPS61103RGER Dual-Output PMIC: Boost + LDO, 500kHz, Obsolete","metaDescription":"Texas Instruments TPS61103RGER dual-output power management IC: boost synchronous converter (3.3V/1.8A) plus LDO (0.9-3.6V/500mA).","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost) Synchronous (1), Linear (LDO) (1)","w/Sequencer":"No","w/LED Driver":"No","w/Supervisor":"No","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"0.8V ~ 3.3V","Number of Outputs":"2","Base Product Number":"TPS611","Frequency - Switching":"500kHz","Operating Temperature":"-40°C~85°C","Supplier Device Package":"24-VQFN (4x4)","Voltage/Current - Output 1":"3.3V, 1.8A","Voltage/Current - Output 2":"0.9V ~ 3.6V, 500mA","Voltage/Current - Output 3":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c603129158f3030aac28693e1934982a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61103RGER/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TPS61103RGER?","answer":"No official replacement order code is listed.
