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
