DESCRIPTION

The MAS9128A is voltage regulator IC with three 2.85V LDO regulators providing voltage regulation for the handset terminal. The output voltages of the three regulators can be modified through a mask option. Two enable/disable pins control the state of 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.
