L7986 Datasheet 3a Step-down Switching Regulator

Manufacturer: STMicroelectronics

Overview: L7986 3 A step-down switching regulator Datasheet - production data VFDFPN10 3 x 3 mm HSOP8 exp.

General Description

The L7986/A is a step-down switching regulator with a 3.7 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 3 A current to the load depending on the application conditions.

The input voltage can range from 4.5 V to 38 V, while the output voltage can be set starting from 0.6 V to VIN.

Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz.
