TLE4254EJ A 数据手册DataSheet 下载

The TLE4254 is a monolithic integrated low-dropout voltage tracking regulator with high accuracy in small PG- DSO-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. With supply voltages up to 40 V, the output voltage follows a reference voltage applied at the adjust input with very high accuracy. The reference voltage applied directly to the adjust input or by an e. g. external resistor divider can be 2.0 V at minimum. The output is able to drive loads up to 70 mA while the device follows with high accuracy the e. g. 5 V output of a main voltage regulator acting as reference.

技术特性Summary of Features:
  • 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 ≤ V I  ≤ +45 V
  • Wide temperature range: -40 °C ≤ T j  ≤ 150 °C
  • Output protected against short circuit to GND and battery
  • Input protected against reverse polarity
  • Overtemperature protection
  • Green product (RoHS compliant)
  • AEC qualified
