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 VOUT = 1.8V (Adjustable), VIN = 2.8V, COUT = 4.7 µF Ceramic (X7R), CIN = 4.7 µF

Ceramic (X7R), IOUT = 1 mA, Temperature = +25°C, VIN = VOUT + 0.6V, RPWRGD = 10 kΩ To VIN.

NOTE: Junction Temperature (TJ) 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.
