Product Details

TPS7B8250QDGNRQ1 is the fixed 5 V, 300 mA DGN-package option in Texas Instruments' TPS7B82-Q1 automotive low-quiescent-current LDO family.

Although the device accepts 3 to 40 V, this 5 V option needs input above 5 V plus load-dependent dropout to regulate during cranking; its 2.7 µA typical light-load current keeps standby draw low.

The enable pin offers a shutdown state for systems that can switch the load off completely, and the specified low-ESR ceramic output-capacitor range gives the board designer flexibility in local decoupling.

The eight-pin thermally enhanced HVSSOP package helps conduct heat when the input-to-output voltage difference is large, a practical limit that must be checked at the full 300 mA load.

TI lists this exact automotive ordering code with a -40 to 150 °C temperature range, so it should be selected against the relevant ambient and junction limits in the data sheet.
