ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Junction Temperature of T J = 25°C only. Minimum and Maximum
limits are guaranteed through test, design, or statistical correlation. Typical values represent the most likely parametric
norm at T J = 25°C, and are provided for reference purposes only. Unless otherwise indicated, V IN = V OUT + 1V, C IN = 4.7μF,
C OUT = 4.7μF or 10μF (Note 1), C BYP = 22nF, T J = 25°C.
