These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values are with respect to GND. 2. Absolute negative voltage on these terminal should not be below –0.5 V. 3. R θJA must be less than 55°C/W, typically achieved with two square inches of copper printed circuit board area connected to the GND terminals for heat dissipation or equivalent. recommended operating conditions MIN TYP MAX UNIT 5-V main input, V(5VCC) 4.5 5.5 V 5-V auxiliary input, V(5VAUX) 4.5 5.5 V 3.3-V auxiliary input, V(3.3VAUX) 3 3.6 V Load capacitance, CL 4.23 4.7 5.17 µF Load current, IL 0 400 mA Ambient temperature, TA 0 70 °C |
