Overview
CALIFORNIA MICRO DEVICES CMPWR150 500mA / 3.
3V SmartOR™ POWER REGULATOR Features • Automatic detection of VCC input supply • Drive output logic to control external switch • Glitch-free output during supply transitions • 500mA output maximum load current • Built-in hysteresis during supply selection • Controller operates from either VCC or VOUT • 8-pin SOIC Thermal or 5-pin TO-263 packages Applications • PCI adapter cards • Network Interface Cards (NIC’s) • Dual power systems • Systems with standby capabilities • See Application Note AP-211 Product Description California Micro Devices SmartORTM CMPWR150 is a low dropout regulator that delivers up to 500mA 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 regulator is ...
