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.

VDOUT (reset output)

---Open-Drain Active-Low reset output---

In general, VDOUT is pulled up by a resistor (100Kohm) to VIN. The AP7217 microprocess (uP) supervisory

circuitry asserts a guaranteed logic-low reset during power-up and power-down. Reset is asserted asserts when

VIN is below the reset threshold and remain asserted for at least tRP after VIN rises above the reset threshold.

As long as VIN is lower than the reset threshold, VDOUT remains at logic "0". When VIN become higher than VTH, a

logic "1" is asserted after a time delay defined by tRP.
