L6984 Datasheet (STMicroelectronics) - synchronous step-down switching regulator

L6984, synchronous step-down switching regulator

The L6984 is a step-down monolithic switching regulator able to deliver up to 400 mA DC.

The output voltage adjustability ranges from 0.9 V.

The fixed 3.3 V VOUT requires no external resistor divider.

The “Low Consumption Mode” (LCM) is designed for applications active during car parking, so it maxi
