Infineon TLE4254EJA

Позитив45V70 мА

Overview

The TLE4254 is a monolithic integrated low-dropout voltage tracking regulator with high accuracy in small PGDSO-8 packages. The IC is designed to supply off-board systems, e. g. sensors in powertrain management systems under the severe conditions of automotive applications. Therefore, the IC is equipped with additional protection functions against reverese polarity and short circuit to GND and battery.

• 70 mA output current capability • Very tight output tracking tolerance to reference • Output voltage adjustable down to 2.0 V • Stable operation with 1 µF ceramic output capacitor • Flexibility of output voltage adjust higher or lower than reference, proportional to the reference voltage (version GA / EJ A) • Status output to indicate short circuits at the output (version GS / EJ S) • Very low dropout voltage of typ. 0.2 V @ maximum output current • Combined reference / enable input • Very low current consumption in OFF mode • Wide input voltage range -20 V ≤ VI ≤ +45 V • Wide temperature range: -40 °C ≤ Tj ≤ 150 °C • Output protected against short circuit to GND and battery • Input protected against reverse polarity • Overtemperature protection • Green product (RoHS compliant) • AEC qualified
