Application Note
Short circuit protection
When VRout pin is shorted to GND or VRout voltage is less than 200mV, short circuit protection will be triggered
and clamp the output current to approximately 50mA.
VD
---Open-Drain Active-Low reset output---
In general, VD
circuitry asserts a guaranteed logic-low reset during power-up and power-down. Reset is asserted asserts when
V
As long as V
logic "1" is asserted after a time delay defined by t
