Voltage Regulator
The voltage regulator needs an external capacitor for compensation and to smooth the distur-
bances from the microcontroller. It is recommend to use an tantalum capacitor with C > 10 F
and a ceramic capacitor with C = 100 nF. The values of these capacitors can be varied by the
customer, depending on the application.
During mode change from Silent to Normal mode, the voltage regulator ramps up to 6V for only
a few microseconds before it drops back to 5V. This behavior depends on the value of the load
capacitor. With 4.7 F, the overshoot voltage has its greatest value. This voltage decreases with
higher or lower load capacitors.
With this special SO8 package (fused lead frame to pin3) an R
thja of 80 K/W is achieved.
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
CC output current IVCC, which is
needed for the application.
Figure 6-1 shows the safe operating area of the ATA6620N.

For programming purposes of the microcontroller it is potentially necessary to supply the VCC
output via an external power supply while the VS pin of the system basis chip is disconnected.
This behavior is no problem for the system basis chip.
