Notes:
For optimum performance the VDD_ANA ball adjacent to VREG_IN should be used for regulator ouput.
(1) _{Regulator output connected to 47nF pure and 4.7µF 2.2Ω ESR capacitors.}
(2) _{Frequency range 100Hz to 100kHz.}
(3) _{1mA to 70mA pulsed load.}
(4) _{Low power mode is entered and exited automatically when the chip enters/leaves Deep Sleep mode.}
(5) _{Regulator is disabled when VREG_IN is either open circuit or driven to the same voltage as VDD_ANA.}
(6) _{Operation up to 5.6V is permissible without damage and without the output voltage rising sufficiently to}
damage the rest of BlueCore3, but output regulation and other specifications are no longer guaranteed
at input voltages in excess of 4.2V.
