The Texas Instruments TLV7103318QDSERQ1 is an automotive-grade dual-output LDO providing fixed 3.3V and 1.8V rails, each rated at 200mA. With 0.2V dropout and 110 µA quiescent current, it delivers efficient, low-noise power in a compact 6-WSON package.
- Dual Outputs: 3.3V and 1.8V in one package.
- Automotive Qualified: AEC-Q100 for reliability.
- Excellent PSRR: 80dB at 10Hz for noise-sensitive loads.
- Low Dropout: 0.2V at 200mA maximizes headroom.
Automotive Infotainment Systems
AEC-Q100 qualified, this dual regulator powers both 3.3V logic and 1.8V I/O from a single device, saving space in head units.
ADAS Sensor Modules
High PSRR (80dB at 10Hz) ensures clean power for camera and radar signal chains in harsh automotive environments.
Dual-Rail Microcontrollers
Many MCUs require separate 3.3V and 1.8V rails; this LDO provides both with 200mA capability.
Battery-Backed Telematics
110 µA quiescent current supports always-on tracking and communication modules.
Compact ECU Power Design
The 1.5x1.5mm WSON package reduces PCB area in engine control units and body controllers.
