TLE4266GHTMA1 Linear Voltage Regulator IC Positive Fixed 1 Output 120mA
The TLE4266GHTMA1 from Infineon is an automotive-grade low-dropout voltage regulator designed for critical power supply applications in harsh automotive environments. This advanced LDO regulator operates from an input voltage range of 3.0V to 45V and delivers a fixed 5V output with ±2% accuracy, capable of supplying up to 400 mA load current while maintaining a low dropout voltage of typically 450 mV at full load.
The voltage regulator features AEC-Q100 Grade 1 qualification and operates across the automotive temperature range of -40°C to +150°C, making it ideal for body control modules, engine management systems, and infotainment applications where reliability under extreme conditions is paramount. The TLE4266GHTMA1 incorporates comprehensive protection features including over-current protection, over-temperature shutdown, reverse polarity protection, and electrostatic discharge (ESD) protection up to 4 kV, providing a robust power management solution for 12V automotive battery systems.
