START
Active-Low, Open-Drain-Fault Flag Output. FLAGV goes low when either an overvoltage or undervoltage
fault occurs at IN. FLAGV is disabled when EN goes high. During startup, FLAGV has a delay of 50ms
after V
Exposed Pad. EP is internally connected to GND. Do not use EP as the only electrical ground connection.
