The boost output delivers a regulated 3.3V at up to 1.8A, while the LDO provides a programmable output from 0.9V to 3.6V at 500mA. The switching frequency is fixed at 500kHz, and the input supply range spans 0.8V to 3.3V, allowing operation from a single-cell alkaline or Li-ion battery down to near end-of-discharge. ## Boost output: 3.3V at 1.8A for system rail The synchronous boost converter (Output 1) is rated for 3.3V at 1.8A — enough headroom to power a small microcontroller, RF transceiver, or sensor cluster from a single-cell battery. ## LDO output: programmable 0.9V to 3.6V at 500mA The linear regulator (Output 2) provides a clean, low-noise rail adjustable from 0.9V to 3.6V at 500mA — suitable for powering analog front-ends, audio codecs, or low-voltage digital cores that need ripple rejection the boost alone cannot deliver. The 20-TSSOP package with 0.65mm pitch is layout-friendly on two-layer boards. No official successor or recommended alternate part number is listed in the product status record.","metaTitle":"TPS61103PWR Dual Boost + LDO Regulator, Obsolete","metaDescription":"TI TPS61103PWR dual-output PMIC: synchronous boost (3.3V/1.8A) + LDO (0.9-3.6V/500mA). 500kHz switching, -40°C to 85°C, 20-TSSOP.","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)","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":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"0.8V ~ 3.3V","Number of Outputs":"2","Base Product Number":"TPS61103","Frequency - Switching":"500kHz","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"20-TSSOP","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":"$2.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c603129158f3030aac28693e1934982a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61103PWR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS61103PWR and TPS61107PWR?","answer":"The TPS61103PWR and TPS61107PWR are both dual-output boost + LDO regulators in the same family, but the TPS61107PWR offers a higher boost output voltage (5V vs 3.3V) and a different LDO output range.
