What are the key features of TPS7A5201WQRTKRQ1?
- AEC-Q100 Grade 1 automotive qualification for -40 °C to 125 °C operation
- Ultra-low typical dropout voltage of 95 mV at 2 A output current
- High output accuracy of ±1% over full temperature range with adjustable output
What is TPS7A5201WQRTKRQ1 used for?
The TPS7A5201WQRTKRQ1 is designed for automotive ADAS, infotainment, and body-control modules that demand a stable, low-noise supply rail under wide temperature swings from -40 °C to 125 °C. Its 2 A capability and 95 mV typical dropout make it ideal for post-regulation of 3.3 V or 1.8 V rails from a 5 V automotive bus. The QFN-20 package suits compact, thermally constrained PCB designs common in advanced driver-assistance systems.

Frequently Asked Questions
What input voltage range does the TPS7A5201WQRTKRQ1 support in automotive 5 V rail applications?
The TPS7A5201WQRTKRQ1 accepts an input voltage from 1.1 V to 6.5 V, making it directly compatible with automotive 5 V power rails. At 2 A load, the typical dropout is only 95 mV, so a 5 V input can cleanly supply a 4.9 V or lower regulated output without losing regulation during load transients.
How does the TPS7A5201WQRTKRQ1 qualify for ADAS and safety-critical automotive designs?
The device is AEC-Q100 Grade 1 qualified, covering -40 °C to 125 °C ambient operation, which meets the thermal requirements of underhood and in-cabin automotive modules. Its ±1% output accuracy over the full temperature range ensures that sensitive DSP and radar supply rails remain within specification throughout the vehicle lifecycle.
What package does TPS7A5201WQRTKRQ1 use and how does it affect PCB thermal management?
The TPS7A5201WQRTKRQ1 comes in a 20-pin QFN package (4 mm × 4 mm footprint). The exposed thermal pad on the underside transfers heat directly to the PCB ground plane, enabling efficient thermal dissipation for sustained 2 A loads without an external heat sink in typical automotive PCB designs.
When would TPS7A5201WQRTKRQ1 be preferred over a fixed-output automotive LDO in a multi-rail ECU design?
Because the output is adjustable, a single TPS7A5201WQRTKRQ1 can replace multiple fixed LDO SKUs in an ECU that needs 1.0 V, 1.2 V, or 1.8 V rails, reducing BOM complexity. The adjustable architecture also allows precise trimming to within ±1% of the target voltage, which fixed-output parts at ±2% accuracy cannot always match for high-precision sensor interfaces.
