NCP580
Ultra−Fast, Low Noise
120 mA CMOS LDO
Regulator with Enable
The NCP580 series of low dropout regulators are designed for
portable battery powered applications which require precise output
voltage accuracy, low quiescent current, and high ripple rejection.
These devices feature an enable function which lowers current
consumption significantly and are offered in the small SC−82AB
package.
A 2.2 mF ceramic capacitor or higher is the recommended value to
be used with these devices on the output pin.
Features
• Ultra−Low Dropout Voltage of 150 mV at 100 mA
• Low Output Noise of 30 mVrms without Noise Reduction Cap
• Excellent Line Regulation of 0.02%/V
• Excellent Load Regulation of 12 mV
• High Output Voltage Accuracy of "1.5%
• Low Iq Current of 90 mA
• Very Low Shutdown Current of 0.1 mA
• Excellent Power Supply Rejection Ratio of 70 dB at f = 1.0 kHz
• Wide Output Voltage Range of 1.5 V to 3.3 V
• Fold Back Protection Circuit
• Fast Dynamic Performance
• Low Temperature Drift Coefficient on the Output Voltage of
"100 ppm/°C
• Input Voltage up to 6.5 V
• These are Pb−Free Devices
T ypical Applications
• Portable Equipment
• Hand−Held Instrumentation
• Camcorders and Cameras

APPLICATION INFORMATION
Input Decoupling
A 1.0 mF ceramic capacitor is the recommended value to
be connected between Vin and GND. For PCB layout
considerations, the traces of Vin and GND should be
sufficiently wide in order to minimize noise and prevent
unstable operation.
Output Decoupling
It is best to use a 2.2 mF or higher capacitor value on the
V
pin. For better performance, select a capacitor with
out
low Equivalent Series Resistance (ESR). For PCB layout
considerations, place the output capacitor close to the
output pin and keep the leads short as possible.
