6. Voltage Regulator
4957I–AUTO–03/11
Figure 6-1.
The voltage regulator needs an external capacitor for compensation and to smooth the distur-
bances from the microcontroller. It is recommended to use an electrolythic capacitor with
C > 1.8µF and a ceramic capacitor with C = 100nF. The values of these capacitors can be var-
ied by the customer, depending on the application.
With this special SO8 package (fused lead frame to pin 3) an R
Therefore, it is recommended to connect pin 3 with a wide GND plate on the printed board to
get a good heat sink.
The main power dissipation of the IC is created from the V
needed for the application.
