For optimum performance, the VDD_ANA ball adjacent to VREG_IN should be used for regulator output,
Regulator output connected to 47nF pure and 4.7µF 2.2Ω ESR capacitors.
Frequency range is 100Hz to 100kHz.
1mA to 70mA pulsed load.
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.
Low power mode is entered and exited automatically when the chip enters/leaves Deep Sleep mode.
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.
