... All devices come standard with adjustable output voltages of 1.2V to 5.0V and fixed output voltages The AS1367 also features a Power-OK output to indicate when the output is within 6% of final value, and also an Enable pin. Shutdown current for the whole regulator is typically 10nA. The device features integrated short-circuit and over current protection ...

... Datasheet - Power-OK The AS1367’s power-ok is built around an N-channel MOSFET. The circuitry monitors the voltage on pin SET and if the voltage goes out of regulation (e.g. during dropout, current limit, or thermal shutdown) the pin POK goes low. If the pin SET is connected to GND an internal resistive-divider is activated and connected to the output. Therefore, the Power- OK functionality can be realised with no additional external components ...

... Power Supply Rejection Ratio The AS1367 are designed to deliver low dropout voltages and low quiescent currents. Power-supply rejection is typically 60dB at 10kHz. To improve power supply-noise rejection and transient response, increase the values of the input and output bypass capacitors ...
