TLE7272-2D

The TLE7272-2D from Infineon Technologies is a monolithic integrated low dropout voltage regulator capable of supplying load currents up to 300 mA. It regulates an input voltage up to 42 V to a precise 5 V output with ±2% accuracy. This device is well-suited for microcontroller supplies due to its integrated reset circuitry, which includes power-on timing and output voltage monitoring.

Key features include ultra-low quiescent current consumption of typically 20 µA, making it ideal for applications permanently connected to VBAT. The device can be further powered down via an Enable input, reducing current consumption to approximately 5 µA. It also incorporates output current limitation and overtemperature shutdown for protection against overload, short circuits, and overheating.

The TLE7272-2D is designed for harsh automotive environments and operates across a wide temperature range from -40 °C to 150 °C. It supports stable operation with ceramic output capacitors as low as 470 nF. The package type is PG-TO252-5, suitable for surface mounting.

Additional protective features include an integrated output sink current circuitry that prevents the output voltage from exceeding 5.5 V, even during reverse current conditions, thus protecting connected devices from overvoltage damage. While suitable for general 5V stabilization, applications requiring extremely low noise levels might consider other Infineon voltage regulator families.
