L9805
The application board can improve noise reduction
in the chip connecting directly pin 42 to pin 9 and
pin 43 to pin 12 using traces as short as possible.
An additional capacitor mounted close to pin 9 and
12 can lead additional improvement.
4.2.1 VDD Short Circuit Protection
The output current of the digital voltage regulator
is controlled by a circuit that limits it to a maximum
value (I
MAXVDD
). When the output current exceeds
this value the VDD voltage starts falling down. Ex-
ternal loads must be chosen taking in account this
maximum current capability of the regulator.
4.3 Analog Section Power Supply
The analog supply voltage is available on VCC
pin. The external 100nF compensation capacitor
should be placed as close as possible to this pin
and AGND pin.
VCC is the reference voltage for the AD conver-
sion and must be used to supply ratiometric sen-
sors feeding AD inputs. Any voltage drop between
VCC pin and the sensor supply pin on the applica-
tion board, will cause the ADC to be inaccurate
when reading the sensor’s output.
4.3.1 VCC Short Circuit Protection
The output current of the analog voltage regulator
is controlled by a circuit that limits it to a maximum
value (I
MAXVCC
). When the output current exceeds
this value the VCC voltage starts falling down. Ex-
ternal loads must be chosen taking in account this
maximum current capability of the regulator.
WARNING: The pin VB2 is not short circuit pro-
tected so a short circuit on this pin will destroy the
device.
