Infineon TLE4473GV55-2: Dual Channel 5V Low-Drop Voltage Regulator
In modern automotive and industrial electronic systems, reliable and efficient power management is critical. The Infineon TLE4473GV55-2 stands out as a high-performance dual-channel low-dropout (LDO) voltage regulator designed to deliver stable 5V outputs with exceptional accuracy and robustness. This IC integrates two independent regulators in a single package, making it an ideal solution for applications requiring multiple redundant or isolated voltage rails.
One of the key features of the TLE4473GV55-2 is its low dropout voltage, which ensures efficient operation even when the input voltage is only slightly above the regulated 5V output. This characteristic is particularly valuable in automotive environments where battery voltage fluctuations are common. Each channel can deliver a continuous output current of up to 450mA, sufficient to power microcontrollers, sensors, and other critical loads.
The device incorporates comprehensive protection mechanisms, including over-current protection, thermal shutdown, and reverse polarity protection. These features enhance system durability and prevent damage under fault conditions. Additionally, the enable function for each channel allows for flexible power management, enabling designers to control power sequencing or shut down unused modules to reduce energy consumption.
With an operating temperature range of -40°C to 150°C, the TLE4473GV55-2 is engineered for harsh environments. Its high immunity to electromagnetic interference (EMI) ensures stable performance in noisy conditions, such as those found in automotive engine compartments or industrial motor drives.
ICGOOODFIND: The Infineon TLE4473GV55-2 combines dual-channel flexibility, robust protection features, and high efficiency in a compact package, making it a top choice for demanding power supply applications in automotive and industrial systems.
