Regulator output connected to 47nF pure and 4.7μF 2.2Ω ESR capacitors. Frequency range 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 CSP, 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 IC enters/leaves Deep Sleep mode
Regulator is disabled when VREG_EN is pulled low. It can also be disabled by VREG_IN when it is
either open circuit or driven to the same voltage as VDD_ANA
