MIC38300A - Ultra-Low Noise 3A Power Module

General Description

The MIC38300A is a 3A current step-down converter that provides the benefits of an LDO in respect to ease of use, fast transient performance, high PSRR, and low noise while offering the efficiency of a switching regulator.

Key Features

  • 3A Continuous Operating Current.
  • Input Voltage Range: 3.0V to 5.5V.
  • Adjustable Output Voltage Down to 1.0V.
  • Output Noise Less Than 5 mV.
  • Ultra-Fast Transient Performance.
  • Unique Switcher Plus LDO Architecture.
  • Fully Integrated MOSFET Switches.
  • Micropower Shutdown.
  • Easy Upgrade from LDO as Power Dissipation Becomes an Issue.
  • Thermal Shutdown and Current-Limit Protection.
  • 4 mm × 6 mm × 1.55 mm LQFN.
