The SmartORTM CMPWR160 combines a Low Dropout Regulator (LDO) with a Power-On Reset (POR) pulse generator, and is intended for Universal Serial Bus (USB) peripherals. To meet the specification requirements of both USB 1.0 and USB 2.0, the CMPWR160 draws a very low quiescent current (35µA), and delivers up to 500mA of load current at a fixed 3.3V output.

FEATUREs
• 3.3V regulated output up to 500mA
• Quiescent current 35µA (typical)
• Shutdown mode current 7µA (typical)
• 30ms active LOW Power-On Reset (POR) pulse
• Thermal overload protection
• Foldback current limiting protection
• Reverse-current protection
• 8 pin SOIC power package

APPLICATIONs
• Bus-powered USB peripherals
• Self-powered USB peripherals
• Portable/battery-powered devices
• Critical power monitoring, hot-insertion devices
