(a) _{For optimum performance, the VDD_ANA ball adjacent to VREG_IN should be used for regulator output,}
(b) _{Regulator output connected to 47nF pure and 4.7µF 2.2Ω ESR capacitors.}
(c) _{Frequency range is 100Hz to 100kHz.}
(d) _{1mA to 70mA pulsed load.}
(e) _{Operation up to 5.6V is permissible without damage and without the output voltage rising sufficiently to damage the rest}
of BlueCore4-ROM Plug-n-Go, but output regulation and other specifications are no longer guaranteed at input voltages
in excess of 4.2V.
(f) _{Low power mode is entered and exited automatically when the chip enters/leaves Deep Sleep mode.}
(g) _{Regulator is disabled when VREG_EN is pulled low. It is also disabled when VREG_IN is either open circuit or driven to}
the same voltage as VDD_ANA.
