Rated to AEC-Q100, it accepts a 2.5V to 6V supply rail — directly from a vehicle battery or a pre-regulated bus — and delivers five independent output rails with a combined supervisor for system reset monitoring. ## Output rail budget and layout implications Output 1 sources up to 1 A from 0.6V to 6V, output 2 delivers 600 mA over the same voltage range, and the three LDOs each provide 400 mA from 1V to 3.6V. The 2.25 MHz switching frequency lets the designer use smaller inductors and ceramic output capacitors, shrinking the total power-stage footprint — a real advantage when the board area is constrained by the module housing. With the bucks running at 2.25 MHz, keep the switch-node loop tight to the inductor and input capacitor to minimise radiated emissions — a common gotcha in automotive EMC testing. For engine-bay or brake-system zones that see sustained 105°C or 125°C ambient, the LP873244RHDTQ1 peer extends to 125°C — but trades two LDOs for a sequencer and a different output count.","metaTitle":"TPS65053IRGERQ1 PMIC, Automotive AEC-Q100, 5 Outputs","metaDescription":"Texas Instruments TPS65053IRGERQ1 automotive PMIC with AEC-Q100 qualification. 2.5V–6V input, 5 outputs (buck + LDO), 2.25 MHz switching, active lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Bulk","Topology":"Step-Down (Buck) Synchronous (2), Linear (LDO) (3)","w/Sequencer":"No","w/LED Driver":"No","w/Supervisor":"Yes","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"2.5V ~ 6V","Number of Outputs":"5","Base Product Number":"TPS65053","Frequency - Switching":"2.25MHz","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"24-VQFN (4x4)","Voltage/Current - Output 1":"0.6V ~ 6V, 1A","Voltage/Current - Output 2":"0.6V ~ 6V, 600mA","Voltage/Current - Output 3":"1V ~ 3.6V, 400mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1000","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65053IRGERQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS65053IRGERQ1 automotive AEC-Q100 qualified?","answer":"Yes, the TPS65053IRGERQ1 is listed under the Automotive, AEC-Q100 series, meaning it has passed the AEC-Q100 stress tests for automotive-grade ICs — suitable for production in passenger vehicles."},{"question":"How many outputs does TPS65053IRGERQ1 have?","answer":"Five outputs total: two synchronous step-down buck converters and three linear LDO regulators.
