• Wide power supply range, VDD_M from 2.2 to 3.6V.
• High current (50 mA) integrated 1.8V regulator to supply the digital core of the SX1441 and external chips,
• Integrated 1.8V analog regulator to supply analog blocks, VREGA output.
• Integrated temperature-compensated voltage reference.
• Battery end-of-life detection, VDDBAT input.
• Mode of operation controller to suppress the need for external power supply switch.
• Ultra low power consumption in OFF mode.
