QUALITY SPECIFICATION
Quality in accordance with UZW-BO/FQ-0601.
TEST INFORMATION
The outputs of the regulators are measured by means of a
selector switch (one by one). In addition, switch SW2 is
only closed when V_bu is greater than V_P; then the internal
switch of the TDA3602 is opened. V_bu (pin 8) can only
withstand a 50 V load dump pulse when switch SW2 is
kept open or when switch SW2 is replaced by a 100 Ω
resistor.
