DESCRIPTION
Ground
No connection
O The OUT terminal provides the regulated output voltage of the device.
O The PG terminal for the fixed voltage option devices is an open drain, active-high output that indicates the status
of VO (output of the LDO). When VO exceeds approximately 90% of the regulated voltage, PG goes to a high
impedance state. It goes to a low-impedance state when VO falls below approximately 90% (i.e. overload condition)
of the regulated voltage. The open drain output of the PG terminal requires a pullup resistor.
I The IN terminal is the power supply input to the device.
