The Texas Instruments TPS7B8450QDCYRQ1 is an automotive-grade, 150mA, 40V low-dropout (LDO) linear regulator. This device is designed for applications requiring a stable 5V output with fast transient response.
Key electrical specifications include an input voltage range of 3V to 40V and a fixed output voltage of 5V. The regulator can supply up to 150mA of output current with a typical dropout voltage of 155mV at 150mA. It offers a high power supply rejection ratio (PSRR) of 65dB at 100kHz and low noise of 280µVrms.
Features include an enable pin for control and protection against over current, over temperature, and under voltage lockout (UVLO). The TPS7B8450QDCYRQ1 is AEC-Q100 qualified for automotive applications, operating from -40°C to 125°C (TA).
This regulator is available in a SOT-223-4 package, suitable for surface mount applications. Its wettable flanks package design aids in automated optical inspection.
