L7983 - 300mA synchronous step-down switching regulator

Description

The L7983 device is a step-down monolithic switching regulator able to deliver up to 300 mA DC based on peak current mode architecture.

The output voltage adjustability ranges from 0.85 V to VIN.

Features

  • 3.5 V to 60 V operating input voltage.
  • Fixed output voltage (3.3 V and 5 V) or adjustable from 0.85 V to VIN.
  • 300 mA DC output current.
  • Dynamic low consumption mode to low noise mode selection.
  • 10 µA operating quiescent current (L7983PU33R, VIN > 24 V, LCM).
  • 2.3 µA shutdown current.
  • 200 kHz to 2.2 MHz programmable switching frequency.
  • Optional spread spectrum (dithering).
  • Internal soft-start.
  • Enable / adju.
