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.
