... The AS1363 features a P-channel MOSFET pass transistor and consumes only a maximum of 200µA of quiescent current under heavy loads as well as in dropout. Shutdown If pin EN is connected to GND the AS1363 is disabled. In shutdown mode all internal circuits are turned off, reducing supply current to 30nA (typ.). For normal operation pin EN must be connected to IN. During shutdown, POK is low. www.austriamicrosystems.com ...
