CALIFORNIA MICRO DEVICES CMPWR101 250mA SmartORTM Regulator with VAUX Switch Features Applications Automatic detection of VCC input supply Glitch-free output during supply transitions Built-in hysteresis during supply selection 250mA output maximum load current Fully integrated VAUX switch Overload current protection Short circuit current protection Operates from either VCC or VAUX 8-pin SOIC package PCI adapter cards Network Interface Cards (NIC’s) Dual power systems Systems with standby capabilities Product Description The California Micro Devices’ SmartORTM CMPWR101 is a low dropout regulator that delivers up to 250mA of load current at a fixed 3.3V output. An internal threshold level (typically 4.1V) is used to prevent the regulator from being operated below dropout voltage. The device continuously monitors the input supply and will automatically disable the regulator when VCC falls below the threshold level. When the r...
