Note 1: Power dissipation is 500 mW when mounted as recommended. Derate at 4.0 mW/°C for operation above 25 °C.
Note 2: Refer to “Definition of Terms.”
Note 3: Ripple rejection and noise voltage are affected by the value and characteristics of the capacitor used.
Note 4: Output noise voltage can be reduced by connecting a capacitor to the noise bypass terminal.
Gen. Note: Parameters with min. or max. values are 100% tested at TA = 25 °C.
Gen. Note: Exceeding the “Absolute Maximum Ratings” can damage the device.
