ONSEMI NCP580SQ30T1G

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.

APPLICATION INFORMATION
Input Decoupling
Output 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.
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.
