(1) When setting V
OUT
to a value other than 0.5 V, connect R
1
and R
2
to the FB pin using 10 kΩ ≤ R
2
≤ 50 kΩ resistors. See Figure 1 for
details of R
1
and R
2
.
(2) Accuracy does not include error on feedback resistors R
1
and R
2
.
(3) TPS7A7001 is not tested at V
OUT
= 0.5 V, 2.3 V ≤ V
IN
≤ 6.5 V, and 500 mA ≤ I
OUT
≤ 2 A because the power dissipation is higher than
the maximum rating of the package. Also, this accuracy specification does not apply to any application condition that exceeds the power
dissipation limit of the package.
