Voltage regulator
The regulator has five operating modes:
●
●
Regulator ON
The regulator ON modes are activated by default on LQFP packages.On WLCSP66
package, they are activated by connecting both REGOFF and IRROFF pins to V
only REGOFF must be connected to V

There are three regulator ON modes:

MR is used in nominal regulation mode (Run)
LPR is used in Stop mode
Power-down is used in Standby mode:
The regulator output is in high impedance: the kernel circuitry is powered down,
inducing zero consumption (but the contents of the registers and SRAM are lost).
Regulator OFF/internal reset ON
On WLCSP66 package, this mode is activated by connecting REGOFF pin to V
IRROFF pin to V
(IRROFF not available).
The regulator OFF/internal reset ON mode allows to supply externally a 1.2 V voltage
source through V
