Frequently Asked Questions
What automotive qualification does TPS7B8833QKVURQ1R2 hold and what does that mean for design-in?
TPS7B8833QKVURQ1R2 is AEC-Q100 Grade 1 qualified, meaning it is tested to withstand automotive temperature extremes of -40 °C to 125 °C junction temperature along with stress tests covering ESD, moisture sensitivity, and life testing per the Automotive Electronics Council standard. This qualification is mandatory for Tier-1 automotive supply chains and simplifies component approval.
How wide is the input voltage range of TPS7B8833QKVURQ1R2, and does it handle load dump transients?
The device accepts 4.3 V to 40 V continuous input, with an absolute maximum of 42 V. This range covers 12 V and 24 V nominal battery rails as well as cold-crank conditions down to 4.3 V. For 40 V transient events such as ISO 7637 load dump pulses, the 40 V rated input provides adequate margin when combined with an upstream TVS clamp.
What is the dropout voltage of TPS7B8833QKVURQ1R2, and how does it affect minimum battery voltage requirements?
Typical dropout voltage is 390 mV at 500 mA output, with a maximum of 575 mV. To keep the output regulated at 3.3 V, the input must stay above 3.875 V typical or 3.875 V worst-case 4.3 V as rated. During engine cranking when the 12 V bus can dip to 6 V, this 575 mV maximum dropout keeps the 3.3 V rail regulation solid.
Which package does TPS7B8833QKVURQ1R2 use and what thermal performance should designers expect?
TPS7B8833QKVURQ1R2 comes in a TO-252 (DPAK) 3-pin surface-mount package with a large exposed drain pad. Thermal resistance junction-to-board is approximately 40 °C/W with adequate PCB copper area. At a 500 mA load from 12 V input, power dissipation is about 4.35 W, requiring a PCB copper area of at least 4 cm² to keep the junction below 125 °C.
