NCP3335A
Ultra High Accuracy,
Low Iq, 500 mA
Low Dropout Regulator
The NCP3335A is a high performance, low dropout 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 mF. The NCP3335A also comes
equipped with sense and noise reduction pins to increase the overall
utility of the device. The NCP3335A offers reverse bias protection.
Features
• High Accuracy Over Line and Load (+0.9% at 255C)
• Ultra−Low Dropout Voltage at Full Load (260 mV typ.)
• No Minimum Output Current Required for Stability
• Low Noise (35 mVrms w/10 nF Cnr and 56 mVrms w/out Cnr)
• Low Shutdown Current (0.07 mA)
• Reverse Bias Protected
• 2.6 V to 12 V Supply Range
• Thermal Shutdown Protection
•www.DataSheet4U.com Current Limitation
• Requires Only 1.0 mF Output Capacitance for Stability
• Stable with Any Type of Capacitor (including MLCC)
• Available in 2.5 V, 2.85 V, 3.3 V, 5.0 V and Adjustable Output
Voltages
• These are Pb−Free Devices
Applications
• PCMCIA Card
• Cellular Phones
• Camcoders and Cameras
• Networking Systems, DSL/Cable Modems
• Cable Set−Top Box
• MP3/CD Players
• DSP Supply
• Displays and Monitors
