Power Management (1/4)
The voltage regulator is probably the device that is used with the majority of applications.
The STM32 ARM® Cortex™-M3 requires a 2.0-3.6V operating voltage supply (VDD), with
a total current up to 150mA (included the I/O current). Depending on the application requirements,
it is possible to use either a linear or a switching voltage regulator.
The following are just a few of the many voltage regulators ST offers:

Power Management (2/4)

on micro hardware to ensure more robustness and reliability to the system. Moreover a tighter

such as portable medical equipment, instrumentation, signal-conditioning systems, sensor interfaces, and

to drive the ADC of the STM32.

Audio Amplifiers
The STM32 ARM® Cortex™-M3 can be used to generate an audio signal in PWM format,

Temperature sensor
The STM32 ARM® Cortex™-M3 has an internal temperature sensor, which
generate a voltage proportional to the variation in temperature. The conversion
range is between 2 V < VDDA < 3.6 V. The temperature sensor is internally
connected to the ADC_IN16 input channel, which is used to convert the sensor
output voltage into a digital value. However, in all those applications where the temperature
sensor has to be remotely placed or tighter accuracy is required a stand-alone sensor must be used.

Digital Circuit
The STM32 ARM® Cortex™-M3 logic inputs are 5 volt tolerant, so a level translator is not needed for a 5V input signal.
Due to the input thresholds, a level translator is necessary with a 1.8V input signal.
The outputs of the STM32 can be configured as open drain and, depending on the reference voltage of the external
pull-up, it is possible to create a level translator, but the output current capability is low. Using a level translator
increases the current capability.
