terminated.
This is the internal reference voltage used to regulate VO. This pin is not connected on fixed output
voltage version of TPS6230xDRC and TPS6232xDRC. Do not connect ADJ pin on fixed output
voltage version of TPS6230xYZD and TPS6232xYED.

On TPS62300 and TPS62320, this pin can also be used as an external control input. The output
voltage is 1.5x the applied voltage at ADJ.
This is the feedback pin of the device. For the adjustable version, an external resistor divider is
connected to this pin. The internal voltage divider is disabled for the adjustable version. This pin is
