NCP3334
High Accuracy,
Ultra Low Iq, 500 mA
Adjustable Low Dropout
Regulator
The NCP3334 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 NCP3334 offers reverse
bias protection.
Features
• High Accuracy Over Line and Load (±0.9% at 25°C)
• Ultra−Low Dropout Voltage
• Low Noise
• Low Shutdown Current (0.07 mA)
• 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)
• No Minimum Output Current Required for Stability
• This is a Pb−Free Device
