TLE4266-2G Description

Short technical summary and product information.

The Infineon TLE4266-2G is a monolithic integrated low-drop fixed voltage regulator capable of supplying loads up to 150 mA. It is specifically designed for automotive electronics, offering robust protection against overloads, short-circuits, and overtemperature conditions. The device is available in a fixed output voltage of either 5.0 V or 3.3 V, with an output voltage tolerance of ±2% or ±3% depending on the specific version and load conditions.

This regulator features a very low quiescent current, consuming less than 1 µA in OFF mode and 40 µA in ON mode, making it ideal for applications requiring minimal power consumption. It operates over a wide temperature range from -40°C to 150°C and includes an inhibit function for on/off control. The TLE4266-2G is supplied in a compact PG-SOT223-4 surface-mount package.

Its suitability for automotive applications is further validated by product qualification according to AEC-Q100/101 standards. The device can accept an input voltage up to 45 V, providing a stabilized output for microprocessor systems and other sensitive electronics under demanding automotive environments.
