1) Input voltage VI required for operation of output Q1
2) Input voltage VI required for operation of output Q2
3) The overtemperature protection is set to > 170 °C. The voltage regulator may not be operated continuously at
170 °C as device reliability will be reduced to 500 h statistic lifetime.
4) Worst case regarding peak temperature, zero airflow; mounted on a PCB 80 × 80 × 1.5 mm3, 35 μm Cu,
5 μm Sn, heat sink area 300 mm2.
Note: In the operating range the functions given in the circuit description are fulfilled.
