What are the key features of TPS7B6950QDCYRQ1?
- Ultra-low IQ design minimizes quiescent current draw for always-on automotive subsystems
- Wide 5.5 V to 40 V input range supports direct connection to automotive 12 V and 24 V battery rails
- AEC-Q100 Grade 1 qualification ensures reliable operation across -40°C to 125°C automotive temperature range
What is TPS7B6950QDCYRQ1 used for?
TPS7B6950QDCYRQ1 is designed for automotive always-on power rails such as body control modules, gateway ECUs, and telematics units that must maintain low standby current. It is also suitable for powering microcontrollers and sensors in engine-bay environments subject to wide voltage transients. The high input voltage capability makes it ideal for direct post-battery regulation without a pre-regulator stage.

Frequently Asked Questions
What is the input voltage range of TPS7B6950QDCYRQ1 and why does it suit automotive 12 V battery systems?
TPS7B6950QDCYRQ1 accepts 5.5 V to 40 V input, with an absolute maximum of 45 V, covering the full range of 12 V and 24 V automotive battery bus voltages including load-dump transients. This wide range eliminates the need for additional clamping components on most automotive ECU designs.
How does the dropout voltage of TPS7B6950QDCYRQ1 affect low-battery performance?
The nominal dropout voltage is 0.7 V and the maximum is 0.8 V, meaning the regulator maintains its output even when the battery sags to within 0.8 V of the set output. This low dropout characteristic is critical for automotive cold-crank scenarios where supply voltage can drop below 6 V.
Which automotive safety standards does TPS7B6950QDCYRQ1 meet and what temperature range is covered?
TPS7B6950QDCYRQ1 carries AEC-Q100 Grade 1 qualification, guaranteeing operation from -40°C to 125°C junction temperature. The Q1 automotive grade designation also confirms it has passed stringent reliability stress tests required for passenger-vehicle production applications.
In what SOT-223 package configuration is TPS7B6950QDCYRQ1 supplied and how does that affect thermal management?
The device ships in a 4-pin SOT-223 package with an exposed pad that provides a low thermal resistance path to the PCB. The small 6.5 mm x 3.5 mm footprint fits tight automotive PCB layouts, and the tab pin allows copper pours to be used as a heat spreader for dissipating up to several hundred milliwatts.
