NOTES
1Ambient 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.
2Accuracy guaranteed using external trim pots.
3For 2.7 V output, the minimum V
IN is 3.2 V.
4Guaranteed by design and characterization.
5Ground currents include the current through R1, R2.
Specifications subject to change without notice.
