Manufacturer: STMicroelectronics

Overview: L5985 2 A step-down switching regulator Datasheet - production data VFQFPN8 3 mm x 3 mm  Industrial: chargers, PLD, PLA, FPGA  Networking: XDSL, modems, DC-DC modules  puter: optical storage, hard disk drive,.

General Description

The L5985 is a step-down switching regulator with a 2.5 A (min.) current limited embedded Power MOSFET, so it is able to deliver up to 2 A DC current to the load depending on the application condition.

The input voltage can range from 2.9 V to 18 V, while the output voltage can be set starting from 0.6 V to VIN.

Having a minimum input voltage of 2.9 V, the device is suitable for a 3.3 V bus.

Key Features

  • 2 A DC output current.
