NOTES
1
Ambient temperature of +85
°
C corresponds to a typical junction temperature of +125
°
C under typical full load test conditions. The formula for Nom V
OUT
is found
in the Output Voltage Selection section.
2
Accuracy guaranteed using external trim pots.
3
For 2.7 V output, the minimum V
IN
is 3.2 V.
4
Guaranteed by design and characterization.
5
Ground currents include the current through R1, R2.
Specifications subject to change without notice.
