CM3019-18 Datasheet PDF - California Micro Devices Corp

Product Description
The CM3019 is a CMOS linear voltage regulator with low quiescent current, very low drop out voltage and better than 1% initial output voltage accuracy.
The quiescent current is typically 150µA at light loads and only 165µA at 500mA. This is 5% more efficient than equivalent Bi-CMOS devices that can waste up to 25mA at 500mA.

FEATUREs
• 500mA output current capability
    • 500mA peak in SOT-23 package
    • 500mA continuous in MSOP package
• 500mV maximum dropout voltage at full load
• Excellent line and load regulation
• Stable with any output capacitor
• Ultra low noise with optional bypass capacitor
• Fast power-up with bypass capacitor
• “Zero” current in Shutdown mode
• Thermal Overload Protection
• Foldback Current Limiting Protection
• Reverse current protection

APPLICATIONs
• Notebook, and palmtop computers
• Cell phones and battery powered devices
• Consumer and personal electronics
• PC Card Vcc and Vpp regulation and switching
