5.5 Low Dropout Voltage Regulator (VDD2)
(Submit Feedback)ATA6847-5050, and ATA6847-5033 provide a voltage regulator with an output voltage of VVDD2 = 3.3V. The VDD2 is powered from the 5V output of the VDD1 regulator. The maximum output current is limited to IVDD2lim.
The ATA6847-3333 provides an inhibit output pin, INH. The purpose of the INH pin is to control external devices, such as external voltage regulators.
When inactive, the INH pin output level is high ohmic. When active, the INH voltage is on VS level.
