The 5V/3.3V regulator is fully integrated on-chip. It requires only a 2.2μF ceramic capacitor for stability and has 100mA current
capability. Using the VMODE pin, the output voltage can be selected to either 5V or 3.3V. Switching of the output voltage during
operation is not intended to be supported. The VMODE pin must be hard-wired to either VINT for 5V or to GND for 3.3V. The
logic HIGH level of the microcontroller interface will be adapted to the VCC regulator voltage.
The output voltage accuracy is in general < ±3%; in the 5V mode with V VBAT < 9V it is limited to < 5%.
To prevent destruction of the IC, the current delivered by the regulator is limited to maximum 100mA to 350mA. The delivered
voltage will break down and a reset may occur.
Please note that this regulator is the main heat source on the chip. The maximum output current at maximum battery voltage
and high ambient temperature can only guaranteed if the IC is mounted on an efficient heat sink.
A power-good comparator checks the output voltage of the VCC regulator and keeps the external microcontroller in reset as
long as the voltage is too low.

The voltage difference between the regulated output voltage and the upper reset threshold voltage is higher than 75mV
(VMODE = HIGH) and higher than 50mV (VMODE = LOW).
