The device provides a power-good indicator (PGOOD) to simplify sequencing and supervision. PGOOD is an open-drain output and a pullup resistor between 5 kΩ and 100 kΩ can be externally connected. The PGOOD switch opens when the VOUT pin voltage is greater than the undervoltage threshold (V_UVTH). The PGOOD pin is pulled down to ground when the VOUT pin voltage is less than V_UVTH, UVLO is less than V_UVLO, VCC is less than V_VCC-UVLO, or during thermal shutdown. A 26-μs rising and 21-μs falling deglitch filter prevents any false pulldown of the PGOOD due to transients. The PGOOD pin voltage cannot be greater than V_VOUT + 0.3 V.
