Texas Instruments TPS73643DBVRG4 is a positive fixed output voltage linear regulator. This component delivers a stable 4.3V output with a maximum current of 400mA. It features a low quiescent current of 550 µA and an input voltage range up to 5.5V. The device offers excellent power supply rejection ratio (PSRR) performance, ranging from 58dB at 100Hz to 37dB at 10kHz. Protection features include over current, over temperature, and reverse polarity. The SOT-23-5 (SC-74A, SOT-753) package is suitable for surface mounting operations. This regulator is commonly utilized in battery-powered devices, portable electronics, and automotive applications where efficient power management is critical. It operates within a temperature range of -40°C to 125°C.
