Description
The LD1117 is a low drop voltage regulator able
to provide up to 800 mA of output current,
available even in adjustable version (V
REF
=
1.25 V). Concerning fixed versions, are offered
the following output voltages: 1.2 V, 1.8 V, 2.5 V,
2.85 V, 3.3 V and 5.0 V. The device is supplied in:
SOT-223, DPAK, SO-8 and TO-220. The SOT-
223 and DPAK surface mount packages optimize
the thermal characteristics even offering a
relevant space saving effect. High efficiency is
assured by NPN pass transistor. In fact in this
case, unlike than PNP one, the quiescent current
flows mostly into the load. Only a very common
10 µF minimum capacitor is needed for stability.
On chip trimming allows the regulator to reach a
very tight output voltage tolerance, within ± 1 % at
25 °C. The adjustable LD1117 is pin to pin
compatible with the other standard. Adjustable
voltage regulators maintaining the better
performances in terms of drop and tolerance.

7 LD1117 adjustable: application note
The LD1117 adjustable has a thermal stabilized 1.25 ± 0.012 V reference voltage between
the OUT and ADJ pins. I
ADJ
is 60 µA typ. (120 µA max.) and ΔI
ADJ
is 1 µA typ. (5 µA max.).
R
1
is normally fixed to 120 Ω. From Figure 9 we obtain:
V
OUT
= V
REF
+ R
2
(I
ADJ
+I
R1
) = V
REF
+ R
2
(I
ADJ
+V
REF
/R
1
) = V
REF
(1 + R
2
/ R
1
) + R
2
x I
ADJ
.
In normal application R
2
value is in the range of few kΩ, so the R
2
x I
ADJ
product could not
be considered in the V
OUT
calculation; then the above expression becomes:
V
OUT
= V
REF
(1 + R
2
/ R
1
).
In order to have the better load regulation it is important to realize a good Kelvin connection
of R
1
and R
2
resistors. In particular R
1
connection must be realized very close to OUT and
ADJ pin, while R
2
ground connection must be placed as near as possible to the negative
Load pin. Ripple rejection can be improved by introducing a 10 µF electrolytic capacitor
placed in parallel to the R
2
resistor (see Figure 10).
