ELECTRICAL SPECIFICATIONS
Unless otherwise specified ,these specifications apply over ,Cin=Cout=10uF,Vin=Vo+1V, Vout=Vfb (for adjustable
version only), and Ta=25 °C. Typical values refer to Ta=25 °C.Low duty cycle pulse testing are used which keeps
junction and case temperatures equal to the ambient temperature.
