Note:
TYPICAL PERFORMANCE CURVES
The graphs and tables provided following this note are a statistical summary based on a limited number of samples and
are provided for informational purposes only. The performance characteristics listed herein are not tested or guaranteed.
In some graphs or tables, the data presented may be outside the specified operating range (e.g., outside specified power
supply range) and therefore outside the warranted range.
Note: Unless otherwise indicated, V IN = V OUT + 0.5V or V IN = 2.3V (whichever is greater), I OUT = 1 mA, C IN = C OUT =
4.7 μF Ceramic (X7R), SHDN = V IN , C DELAY = Open, Fixed Output Version, and T A = +25°C.
Note: Junction Temperature (T J ) is approximated by soaking the device under test to an ambient temperature equal to
the desired junction temperature. The test time is small enough such that the rise in Junction Temperature over the
Ambient temperature is not significant.
