The output voltages of the three regulators can be modified through a mask option. Two enable/disable pins control the state of A@6UVS@T the regulators. In order to save power the device goes into sleep mode when all regulators are disabled. An internal thermal protection circuit prevents the device from overheating. The maximum output current is limited internally. 6QQGD86UDPI • 2.85V regulators at 100mA, 70mA and 50mA • Output accuracy
