What are the key features of TPS7A6650HQDGNRQ1?
- AEC-Q100 Grade 1 automotive qualified LDO rated for -40°C to +125°C junction temperature operation
- Ultra-low quiescent current enabling standby power budgets well below 100 µA in always-on 12 V automotive rails
- Wide 5.5 V to 40 V input range with 0.24 V maximum dropout at 150 mA for direct connection to 12 V and 24 V vehicle buses
What is TPS7A6650HQDGNRQ1 used for?
The TPS7A6650HQDGNRQ1 is designed for automotive always-on power domains such as body control modules, gateway ECUs, and ADAS sensor nodes that must maintain active voltage rails during engine-off and key-off events. Its 40 V input rating and AEC-Q100 Grade 1 qualification make it suitable for direct connection to 12 V automotive battery buses subject to load-dump transients up to 40 V.

Frequently Asked Questions
What is the input voltage range and dropout voltage of TPS7A6650HQDGNRQ1 for 12 V automotive battery operation?
The TPS7A6650HQDGNRQ1 accepts input voltages from 5.5 V to 40 V, covering cold-crank conditions as low as 6 V and load-dump transients up to 40 V. With only 0.13 V typical dropout at 150 mA, it maintains regulated output even when the battery voltage dips to within 130 mV of the output rail.
How does TPS7A6650HQDGNRQ1's ultra-low IQ benefit an automotive gateway ECU that must remain active during engine-off?
The TPS7A6650HQDGNRQ1's ultra-low quiescent current—typically in the single-digit µA range—minimizes battery drain over a parked 30-day period. For a 70 Ah automotive battery, an always-on ECU consuming less than 10 µA from the LDO adds negligible standby drain, extending battery life between engine starts.
What AEC-Q100 grade is TPS7A6650HQDGNRQ1 qualified to and what temperature range does that cover?
The TPS7A6650HQDGNRQ1 is AEC-Q100 Grade 1 qualified, covering junction temperatures from -40°C to +125°C. This grade is required for under-hood automotive electronics exposed to engine-bay heat, ensuring reliable regulation across the full automotive temperature range.
Can TPS7A6650HQDGNRQ1 replace a standard 12 V to 5 V buck converter in a cost-sensitive automotive node?
For loads of 150 mA or less, the TPS7A6650HQDGNRQ1 LDO can replace a switching converter, trading efficiency (power dissipation up to 1.05 W at 150 mA with 12 V input) for lower EMI, reduced BOM, and simpler PCB layout in the 8-pin SOIC-8 package without external inductors.
