General Description

The MIC38300 is a 3A peak, 2.2A continuous output current step down converter. This is the first device in a new generation of HELDO® (High-Efficiency Low Dropout) regulators that provide 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.

Features

• 3A peak output current

• 2.2A continuous operating current

• Input voltage range: 3.0V to 5.5V

• Adjustable output voltage down to 1.0V

• Output noise less than 5mV

• Ultra-fast transient performance

• Unique switcher plus LDO architecture

• Fully-integrated MOSFET switches

• Micro-power shutdown

• Easy upgrade from LDO as power dissipation becomes an issue

• Thermal shutdown and current-limit protection

• 4mm × 6mm × 0.9mm MLF package

Applications

• Point-of-load applications

• Networking, server, industrial power

• Wireless base-stations

• Sensitive RF applications
