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. http://onsemi.com MARKING DIAGRAM • • • • • • • • • • • • • • 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 4 1 M SC−82AB SQ SUFFIX CASE 419C Features xxx M G G 1 xxx = Device Code M = Date Code* G = Pb−Free Package (Note: Microdot may be in either location) *Date Code orientation and/or position may vary depending upon manufacturing location.

For PCB layout considerations, the traces of Vin and GND should be sufficiently wide in order to minimize noise and prevent unstable operation. It is best to use a 2.2 mF or higher capacitor value on the Vout pin. For better performance, select a capacitor with 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.
