L4938ED Standard Functions, Voltage Regulators

The L4938ED and L4938EPD are monolithic integrated dual voltage regulators with two very low dropout outputs and additional functions such as power-on reset and input voltage sense. They are designed for supplying microcomputer controlled systems especially in automotive applications.

技术特性
  • Enable and sense inputs (EN, SI) protected against negative transients down to -5 V
  • Reset threshold adjustable from 3.8 V to 4.7 V
  • Extremely low quiescent current, 65 μA (less than 90 μA) in standby mode
  • Operating DC supply voltage range 5 V - 28 V
  • Operating transient supply voltage up to 40 V
  • High precision standby output voltage 5 V ± 1% with 100 mA current capability
  • Output 2 voltage 5 V ± 2% with 400 mA current capability (ADJ wired to VOUT2)
  • Output 2 voltage adjustable by external voltage divider
  • Output 2 disable function for standby mode
