Note 1: Power dissipation is 400 mW when mounted as recommended. Derate at 3.2 mW/°C for operation above 25 °C.
Note 2: Refer to “Definition of Terms.”
Note 3: Please refer to the Applications Section for more information.
Note 4: Ripple rejection is measured at VR = 200 mVrms, VIN = VOUT(TYP) + 2 V, IOUT = 10 mA, CL = 2.2 µF, f = 100 Hz.
Note 5: The minimum operating voltage for VIN can be 1.8 V. Also, the minimum voltage required for VIN is VIN = VDROP + VOUT. As a result, operating at
VOUT £ 2.0 V at the minimum input operating voltage is not preferred.
Gen. Note: Parameters with min. or max. values are 100% tested at TA = 25 °C.
