... GND 8.2 Shutdown If pin EN is connected to GND the AS1364 is disabled. In shutdown mode all internal circuits are turned off, reducing supply current to 10nA (typ). For normal device operation pin EN must be connected to IN. During shutdown, POK goes low. When in shutdown, a 5k (typ) discharge path is connected between the output pin and ground. ...

... AS1364 Datasheet - Application Information 9.1 Dropout Voltage Dropout is the input to output voltage difference, below which the linear regulator ceases to regulate. At this point, the output voltage change follows the input voltage change. Dropout voltage may be measured at different currents and, in particular at the regulator maximum one. From this is obtained the MOSFET maximum series resistance over temperature etc ...

... Larger output capacitor values (10µF max) help to reduce noise and improve load transient-response, stability and power-supply rejection. 9.6.3 Input Capacitor An input capacitor required for stability recommended that a 4.7µF capacitor be connected between the AS1364 power supply IN input pin V and ground (capacitance value may be increased without limit subject to ESR limits). This capacitor must be located at a distance ...

... To prevent operation under extreme fault conditions, such as a permanent short circuit at the output, thermal protection is built into the device. Die temperature is measured, and when a 170ºC (AS1364) threshold is reached, the device enters shutdown. When the die cools sufficiently, the device will restart (assuming input voltage exists and the device is enabled). Hysteresis of 20ºC prevents low frequency oscillation between start- up and shutdown around the temperature threshold ...
