NCP3334A
Ultra High Accuracy,
Low Iq, 500 mA
Low Dropout Regulator
The NCP3334A is a high performance, low dropout regulator with
accuracy of ±0.9% over line and load. This device features ultra−low
quiescent current and noise which encompasses all necessary
characteristics demanded 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 mF. The NCP3334A offers reverse bias protection. The device is
available in a small 3x3 mm WDFN8 package.
Features
• High Accuracy Over Line and Load (±0.9% at 25°C)
• Ultra−Low Dropout Voltage at Full Load
• No Minimum Output Current Required for Stability
• Low Noise
• Low Shutdown Current
• Reverse Bias Protected
• 2.6 V to 12 V Supply Range
• Thermal Shutdown Protection
• Current Limitation
• Requires Only 1.0 mF Output Capacitance for Stability
• Stable with Any Type of Capacitor (including MLCC)
• These are Pb−Free Devices
Applications
• Telecom Applications
• Cellular Base Stations
• Camcoders and Cameras
• Networking Systems, DSL/Cable Modems
• Cable Set−Top Box
• MP3/CD Players
• DSP Supply
• Displays and Monitors
