Description

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.

Key Features

  • 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

Applications
