The AEC-Q100 qualification targets it for under-hood and chassis-domain electronic control units (ECUs) where a single 5.6 V to 40 V battery rail must be split into multiple regulated supplies. ## Rail budget: 5.3 V buck plus three LDOs Output 1 is a 5.3 V buck rated at 1.2 A — sized for the main MCU core or a 5 V sensor supply with headroom. Outputs 2 and 3 are 5 V and 3.3 V LDOs at 350 mA each, suitable for analog front-end or I/O rail needs. The buck runs at 2 MHz to 3 MHz, keeping the inductor small enough for the 4.40 mm-wide HTSSOP footprint. ## Built-in supervisor, no sequencer The PMIC includes an integrated voltage supervisor for monitoring the output rails, but does not include a power-up sequencer or an integrated LED driver. The supervisor simplifies the external watchdog circuit for an automotive safety-oriented design. ## 24-HTSSOP with exposed pad — thermal design note The 0.173-inch (4.40 mm) body width and 0.65 mm pin pitch are standard for hand-solder or reflow assembly.","metaTitle":"TPS65300QPWPRQ1 Automotive PMIC, Buck + 3 LDOs, AEC-Q100","metaDescription":"Texas Instruments TPS65300QPWPRQ1 automotive PMIC: one step-down buck (5.3 V, 1.2 A) and three LDOs, 5.6 V to 40 V input, -40°C to 125°C, AEC-Q100.
