function

• Input voltage: 1.6V to 5.5V
• Output voltage: 0.6V~5.0V
• Voltage accuracy: ±0.7% @ 25ºC [±1% (when considering load current and temperature)]
• Low quiescent current [Iq]: 35µA typ
• High PSRR: 85 dB (typ)
• Low noise: 10 uVRMS (fixed output version)
• Power Good output available
• Output voltage slew rate time selectable

The 0.5A LDO, NCP189, features low noise and high PSRR.
In addition, stable operation is possible with small ceramic capacitors of 4.7uF for the input and output capacitors.
The package is a very small 2mm x 2mm​ ​WDFNW-6.
The low noise and high PSRR can be seen in the graph below in the datasheet.

It also details the selectable output voltage slew rate times.
The NCP189 has internal output voltage slew rate control.

After an enable event, approximately 85us of dead time is required for all internal LDO blocks to start up properly.
Once this time is over, the output voltage will begin to ramp from zero to the fixed output voltage and the amount of time required to settle to the output voltage depends on the voltage option and slew rate.
