NCP3337
Ultra High Accuracy, Low
Iq, 500 mA with Power
Good Low Dropout
Regulator
The NCP3337 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 NCP3337 also comes
equipped with sense and noise reduction pins to increase the overall
utility of the device. The NCP3337 offers reverse bias protection.
Features
• High Accuracy Over Line and Load (±0.9% at 25°C)
• Ultra−Low Dropout Voltage at Full Load (260 mV typ)
• No Minimum Output Current Required for Stability
• Low Noise (33 mVrms w/10 nF Cnr and 52 mVrms w/out Cnr)
• Low Shutdown Current (< 1 mA)
• Reverse Bias Protected
• 2.9 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)
• Available in 1.8 V, 2.5 V, 3.3 V, 5.0 V and Adjustable Output
Voltages
• Power Good Output
• These are Pb−Free Devices
Applications
• PCMCIA Card

2. Performance guaranteed over the operating temperature range by design and/or characterization, production tested at TJ = TA = 25°C. Low
duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.
3. TA must be greater than 0°C.
4. Maximum dropout voltage is limited by minimum input voltage Vin = 2.9 V recommended for guaranteed operation.
