Frequently Asked Questions
What are the key specifications of the TPS7B8650QKVURQ1?
The TPS7B8650QKVURQ1 provides 500mA output current with a fixed output voltage, accepts up to 40V input (42V absolute maximum), has a typical dropout voltage of only 0.37V (0.575V maximum), and operates from -40°C to 150°C, all in a 5-pin TO-252 surface-mount package with an integrated power-good signal.
Is the TPS7B8650QKVURQ1 AEC-Q100 qualified for automotive use?
Yes, the TPS7B8650QKVURQ1 carries the AEC-Q100 automotive qualification (indicated by the RQ1 suffix) and is designed for use in automotive applications. It meets the reliability and temperature requirements of modern vehicle electronics, supporting designs from -40°C to 150°C ambient temperature.
Why is ultra-low quiescent current important in automotive LDO regulators?
Automotive systems often have always-on subsystems such as keyless entry, immobilizers, and telematics modules that must remain powered even when the ignition is off. Ultra-low quiescent current ensures these modules draw minimal current from the vehicle battery over days or weeks, preventing battery drain and meeting OEM dark-current specifications.
What package does the TPS7B8650QKVURQ1 use and how many pins does it have?
The TPS7B8650QKVURQ1 is housed in a 5-pin TO-252 (DPAK) surface-mount package (JESD-30 code R-PSSO-G4), which provides good thermal dissipation via the exposed pad and is widely compatible with standard automotive PCB assembly processes and reflow soldering.
What input voltage range does the TPS7B8650QKVURQ1 support?
The TPS7B8650QKVURQ1 operates from a minimum input voltage of 6V up to 40V continuously, with a 42V absolute maximum rating, making it capable of withstanding automotive load dump transients and cold-crank voltage dips while maintaining stable regulation across the full automotive battery voltage range.
