Details

The TPS7A4501DCQ is a low-dropout linear regulator designed to provide up to 1A of output current. It operates with an input voltage range of 2.7V to 5.5V and produces a fixed output voltage with an accuracy of ±2% over the temperature range of -40°C to 125°C. The device features a dropout voltage as low as 200mV at 1A load, making it suitable for applications where a small voltage drop is crucial. The TPS7A4501DCQ also comes equipped with various protection features, including thermal shutdown, overcurrent protection, and reverse polarity protection. It is available in a small 6-pin SOT-223 package, making it suitable for space-constrained applications. Additionally, the device offers high PSRR and low output noise, making it ideal for powering noise-sensitive components in applications such as industrial sensors, data acquisition systems, and portable medical devices.
