Product Overview

The L7986A is a step-down Switching Regulator with a 3.7A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 3A current to the load depending on the application conditions. The input voltage can range from 4.5 to 38V, while the output voltage can be set starting from 0.6V to VIN. Requiring a minimum set of external components, the device includes an internal 250kHz switching frequency oscillator that can be externally adjusted up to 1MHz.
  • Internal soft-start and enable
  • Low dropout operation - 100% duty cycle
  • Voltage feed-forward
  • Zero load current operation
  • Over-current and thermal protection
