"TLE42644G 英飞凌芯片中文版规格书手册：汽车功率数据表"

The TLE42644G is an automotive power low dropout fixed voltage regulator produced by Infineon Technologies. This device is designed to provide a stable output voltage of 5V with tight regulation, making it suitable for applications with low power requirements. The TLE42644G features a very low dropout voltage, ensuring that the output voltage remains stable even when the input voltage falls close to the desired output level. Additionally, this regulator has a very low current consumption of only 40µA, making it highly efficient and suitable for battery-operated applications. One of the key features of the TLE42644G is its output current limitation, which protects the device from overload conditions that could potentially damage the connected circuitry. In addition, this regulator also includes reverse polarity protection, preventing damage in case the input power supply is connected incorrectly. The TLE42644G also incorporates overtemperature protection, which shuts down the device in case it reaches an unsafe operating temperature, preventing damage and ensuring the safety of the connected circuit. The TLE42644G is housed in a PG-SOT223-4 package, making it easy to integrate into a variety of automotive and industrial applications. The package is marked with the product code 42644 for easy identification. This regulator is capable of providing a consistent output voltage of 5V±2% for output currents of up to 50mA, or 5V±3% for currents up to 100mA. Overall, the TLE42644G is a reliable and efficient voltage regulator that is well-suited for automotive and industrial applications where a stable 5V power supply is required. With its low dropout voltage, low current consumption, and built-in protection features, the TLE42644G provides a cost-effective solution for powering sensitive electronic devices in a variety of challenging environments.
