PRODUCTION DATA.
Use well-regulated supplies on IN1 and IN2 that have sufficient capacitance for the application load transients. As close as possible to the device, use a 0.1-μF ceramic bypass capacitor between IN1 and GND for the first power supply input and a 0.1-μF ceramic bypass capacitor between IN2 and GND for the second power supply input. The recommendation is to place a high-value capacitor between OUT and GND when the output load is heavy. This precaution reduces power-supply transients that may cause ringing on the input or voltage drops during load transients or supply input transitions. Additionally, bypassing the output with a 0.01-μF to 0.1-μF ceramic capacitor may reduce high-frequency emissions.
