NCP3334: Linear Voltage Regulator, LDO, Low Iq, 500 mA (Adjustable Output)

Product Description
The NCP3334 is a high performance, low dropout (LDO) linear voltage regulator. With accuracy of +/-0.9% over line and load and ultra-low quiescent current and noise it encompasses all of the necessary features required by today's consumer electronics. This unique device is guaranteed to be stable without a minimum load current requirement and stable with any type of capacitor as small as 1.0 µF. The NCP3334 offers reverse bias protection.
Features
 
  • High Accuracy Over Line and Load (±0.9% at 25°C)
  • Low Dropout Voltage of 340 mV maximum at 500 mA
  • Low Noise of 38 µVrms
  • Low Shutdown Current (0.07 µA)
  • Reverse Bias Protected
  • 2.6 V to 12 V Supply Range
  • Thermal Shutdown Protection
  • Current Limitation
  • Requires only 1.0 uF Output Capacitance for Stability
  • Stable with any type of capacitor, including MLCC
Applications
  • PCMCIA Card
  • Cellular Phones
  • Camcoders and Cameras
  • Networking Systems, DSL/Cable Modems
  • Cable Set-Top Box
