L4979D Overview

L4979D and L4979MD are low dropout linear regulators with microprocessor control functions such as low voltage reset, watchdog, on/off control. Typical quiescent current is 100 µA in Datasheet - production data very low output current mode and enabled regulator. The devices drop to 6 µA with not enabled regulators.

L4979D Key Features

  • AEC-Q100 qualified
  • Low quiescent current (6 µA typ. @ 25 °C with enable low)
  • High precision output voltage (+/-2%)
  • Low dropout voltage less than 0.5 V
  • Reset circuit sensing the output voltage down
  • Programmable reset pulse delay with external capacitor
  • Watchdog
  • Programmable watchdog timer with external
  • Thermal shutdown and short circuit protection
  • Automotive temperature range (Tj = -40 °C to 150 °C)
