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
