9.6.6 Turn On Time
This specification defines the time taken for the LDO to awake from shutdown. The time is measured from the release of the enable pin to the
time that the output voltage is within 5% of the final value. It assumes that the voltage at V
is stable and within the regulator Min and Max limits.
IN
Shutdown reduces the quiescent current to very low, mostly leakage values (<1µA).
9.6.7 Thermal Protection
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.
