The device has an integrated power-on reset (POR)/power-down reset (PDR) circuitry. It is
always active, and ensures proper operation starting from/down to 2 V. The device remains

Voltage regulator
The regulator has three operation modes: main (MR), low power (LPR) and power down.

This regulator is always enabled after reset. It is disabled in Standby mode.
Low-power modes
The STM32F101xC, STM32F101xD and STM32F101xE access line supports three low-
power modes to achieve the best compromise between low power consumption, short
startup time and available wakeup sources:

MR is used in the nominal regulation mode (Run)
LPR is used in the Stop modes.
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)
Sleep mode
In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can
wake up the CPU when an interrupt/event occurs.
Stop mode
Stop mode achieves the lowest power consumption while retaining the content of
SRAM and registers. All clocks in the 1.8 V domain are stopped, the PLL, the HSI RC
and the HSE crystal oscillators are disabled. The voltage regulator can also be put
either in normal or in low power mode.
