Load capacitances in the range 0.002 μF − 0.047 μF cause the output overshoot to exceed 100 mV. 2 Operation at high ambient temperature requires a thermally optimized PCB layout (see the Applications section). In systems with limited or no airflow, the maximum ambient operating temperature is limited to 70°C with the thermal protection enabled, VFS = 4 V, data update rate = 85 Ms/s. Operation at 85°C ambient temperature requires the thermal protection circuit turned disabled (TSW = LOW). |
