Note 1: When mounted as recommended. Derate at 4.8 mw/°C for SOT-23L and 6.4 mw/°C for SOT-89 packages 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 a noise pass terminal.
Gen Note: Parameters with min. or max. values are 100% tested at TA = 25 °C.
Gen Note: For Line Regulation, typ. and max. is changed to VOUT > 5.6 V.
