| 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.

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.
