NCP4561 regulator equivalent, ultra low-noise low dropout voltage regulator.
* Ultra Low−Noise: 150 nV/√Hz @ 100 Hz, 40 mVRMS 100 Hz −
100 kHz Typical, Iout = 60 mA, Co = 1.0 mF
* Fast Response Time from OFF to ON: 40 ms Typical at a 200 H.
The NCP4561 also hosts a novel architecture which prevents excessive undershoots when the regulator is the seat of fast.

1
ON/OFF
Shuts or
wakes−up the IC
2
GND
The IC’s ground
3 NC None
4 Vout Delivers the output voltage
5 Vin Powers the IC
Description A 900 mV level on this pin is sufficient to start the IC. A 150 mV shuts it dow.
