ST92F124/F150/F250 - GENERAL DESCRIPTION
1.3 VOLTAGE REGULATOR
The internal Voltage Regulator (VR) is used to
power the microcontroller starting from the exter-
nal power supply. The VR comprises a Main volt-
age regulator and a Low-power regulator.
– The Main voltage regulator generates sufficient
current for the microcontroller to operate in any
mode. It has a static power consumption (300
µA typ.).
– The separate Low-Power regulator consumes
less power is used only when the microcontrol-
ler is in Low Power mode. It has a different de-
sign from the main VR and generates a lower,
non-stabilized and non-thermally-compensated
voltage sufficient for maintaining the data in
RAM and the Register File.
For both the Main VR and the Low-Power VR, sta-
bilization is achieved by an external capacitor,
connected to one of the VREG pins. The minimum
recommended value is 300 nF, and care must be
taken to minimize distance between the chip and
the capacitor. Care should also be taken to limit
the serial inductance to less than 60nH.

IMPORTANT: The VREG pin cannot be used to drive external devices.

Note: Pin 31 of PQFP100 or pin 28 of LQFP100 can be left unconnnected. A secondary stabilization net-
work can also be connected to these pins.
