TPS7A6333QDRKRQ1 LDO regulator
General DescriptionThe TPS7A6333QDRKRQ1 is an automotive-grade, fixed-output low-dropout (LDO) regulator from Texas Instruments, offering a robust combination of wide input voltage, ultra-low quiescent current, and high reliability for 12V/24V automotive and industrial systems. This device delivers a fixed 3.3V output at up to 300mA, supports an input voltage range from 4V to 40V with 45V transient tolerance, and features a typical dropout voltage of 300mV at 150mA, ensuring stable operation under heavy load conditions. It boasts an ultra-low quiescent current of 35µA and a sleep current below 2µA, significantly extending battery life in always-on and standby applications.
Housed in a thermally enhanced 10-pin VSON package (3x4mm) with exposed pad, it minimizes board space while optimizing thermal dissipation, and is qualified to AEC-Q100 with an operating temperature range of -40°C to +125°C for harsh environments. Integrated protection features include foldback overcurrent, thermal shutdown, and watchdog timer, alongside power-good and reset functions, enhancing system safety and monitoring capability.
The TPS7A6333QDRKRQ1 is primarily used in automotive electronics such as ECU, infotainment, ADAS, and body control modules, providing stable 3.3V power for microcontrollers, sensors, and communication interfaces. It serves as a power supply for industrial control systems, PLCs, sensor transmitters, and motor drivers, leveraging its wide input range and robust protection features. It is ideal for battery-powered devices including portable test equipment, wireless sensor nodes, and medical instruments, benefiting from ultra-low quiescent current and high efficiency. It is applied in telecommunication infrastructure, PoE devices, and factory automation systems requiring reliable, low-noise 3.3V power regulation.
