• Manufacturer: Anpec Electronics Corporation

APA2071
Application Information (Cont.)
Thermal Consideration (Cont.)
The APA2071 is designed with a thermal shutdown pro-
tection that turns the device off when the junction tem-
perature surpasses 150°C to prevent damaging the IC.
Layout Consideration
1. All components should be placed close to the APA2071.
2. The output traces should be short, wide (>50mil), and
3. The input trace should be short and symmetric.
4. The power trace width should be greater than 50mil.
5. The APA2071’ s GND pin should be soldered on ground
