Infineon TLE 4274 3.3V/2.5V Voltage Regulator Datasheet
The TLE 4274 series voltage regulator is offered in SOT‑223 and TO‑252 packages and provides selectable 3.3 V or 2.5 V output with a tolerance of ±4 %. It features very low quiescent current, short‑circuit protection, reverse‑polarity protection, and an over‑temperature shutdown circuit, making it suitable for automotive electronics.
The device operates from an input voltage range of 4.7 V to 40 V, delivers up to 400 mA continuous output current, and requires external input and output capacitors for stability. Detailed absolute‑maximum ratings, electrical characteristics, and typical performance curves are provided in the datasheet.
