TLE42744DV33 Description

Short technical summary and product information.

The Infineon TLE42744DV33 is a monolithic integrated low dropout voltage regulator designed for load currents up to 400 mA. It provides a stable output voltage of 3.3 V with a precision of ±2% and can handle input voltages up to 40 V.

This device is engineered for the demanding environment of automotive applications, featuring built-in protection against overload, short-circuit, and overtemperature conditions through output current limitation and overtemperature shutdown circuits. Its very low quiescent current makes it suitable for applications permanently connected to VBAT.

The TLE42744DV33 operates within a wide temperature range from -40°C to 150°C. It is supplied in a PG-TO252-3 package, suitable for surface mount applications.

Key features include a very low dropout voltage, output current limitation, reverse-polarity protection, and overtemperature shutdown, making it a robust choice for various automotive and general-purpose applications requiring a stabilized 3.3 V supply.
