Key Features
- Wide 6 V to 40 V input voltage range with 42 V absolute maximum handles automotive load-dump transients and 24 V truck battery rails without external protection components
- Low typical dropout voltage of 0.37 V at 500 mA output current maximises efficiency headroom on regulated ECU 5 V rails powered from a nominal 6 V post-converter bus
- AEC-Q100 automotive qualification in a TO-252-5 (D-PAK) through-hole-compatible SMD package ensures reliable operation from -40 °C to 125 °C in powertrain and body-control modules
Applications
The TPS7B8650QKVURQ1R2 provides a stable 5 V regulated rail for automotive body-control modules, gateway ECUs, and ADAS processing boards powered from a 12 V or 24 V vehicle battery. Its 40 V maximum input rating handles load-dump events without external clamp circuitry, reducing system-level protection component count. Industrial equipment operating from unregulated 24 V DC bus rails, such as PLC I/O modules and motor-drive gate-driver boards, also benefit from its 500 mA output and AEC-Q100-grade reliability.

Frequently Asked Questions
What input voltage range does the TPS7B8650QKVURQ1R2 support, and how does it handle automotive load-dump transients?
The TPS7B8650QKVURQ1R2 accepts input voltages from 6 V to 40 V, with a 42 V absolute maximum rating. This headroom allows it to survive ISO 7637-2 load-dump pulses up to 40 V on a 12 V automotive battery bus without requiring an external TVS diode, simplifying the BOM and reducing board area.
What is the dropout voltage of the TPS7B8650QKVURQ1R2 at full load, and why does it matter for efficiency?
At 500 mA output current, the TPS7B8650QKVURQ1R2 has a typical dropout voltage of 0.37 V and a maximum of 0.575 V. On a 5 V output rail, this means the regulator maintains regulation with an input as low as 5.575 V maximum, preserving regulation during battery voltage dips in start-stop automotive systems below 6 V.
What automotive qualification does the TPS7B8650QKVURQ1R2 carry, and what temperature range does it support?
The TPS7B8650QKVURQ1R2 is AEC-Q100 qualified, covering the automotive temperature grade for operation from -40 °C to 125 °C junction temperature. This rating meets OEM requirements for under-hood ECU applications including engine management, transmission control, and ADAS sensing modules exposed to extreme thermal cycles.
What package does the TPS7B8650QKVURQ1R2 use, and how does it facilitate thermal management at 500 mA?
It is housed in a TO-252-5 (D-PAK, JESD-30 code R-PSSO-G4) SMD package with an exposed tab for heatsinking. At 500 mA output with a 7 V input-to-output differential, the dissipation is 3.5 W; soldering the tab to a 25 cm² copper pour on a 2-layer PCB typically keeps junction temperature below 125 °C in still air.
