MCP73831/2 2.0 TYPICAL PERFORMANCE CURVES Note:
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, VDD = [VREG(typical) + 1V], IOUT = 10 mA and TA= +25°C, Constant-Voltage mode.
