DESCRIPTION
The LD1117 is a LOW DROP Voltage Regulator
able to provide up to 800m A of Output Current,
available even in adjustable version (V re f= 1.25V).
Concerning fixed v ers ions, are offered t he
following Output Voltages: 1.2V,1.8V,2.5V,2.85V,
3.0V 3.3V and 5.0V. The 2.85V type is ideal for
SCSI-2 lines active termination. The device is
supplied in: SOT-223, DPAK, SO-8, TO -220 and
TO-220FM. 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 commo n 10µF minim um
capacitor is ne eded for stability. On chip trimming
allows the regulator to reach a very tight out put
voltage tolerance, within ± 1% at 25°C. The
ADJUSTABLE LD1117 is pin to pin compatible
with the other standard. Adjustable voltage
regulators maintainin g the better performances in
terms of D rop and Tolerance.

ABSOLUTE MAXIMUM RAT INGS
Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is
not implied. Over the above suggested Max Power Dissipation a Short Circuit could definitively damage the device.

LD1117 ADJUSTABLE: APPLICATION NOTE
The LD1117 ADJU S TA BLE has a thermal stabilized 1. 25±0.012V ref erenc e voltage between the OUT
and ADJ pins. I
ADJ
is 60µA typ. (120µA max.) and ∆I
ADJ
is 1µA typ. (5µA max.).
R1 is normally fixed to 120Ω. From figure 7 we obtain:
V
OUT=VREF
+R2(I
ADJ+IR1
)=V
REF
+R2(I
ADJ+VREF
/R1) = V
REF
(1 + R2 / R1) + R2 x I
ADJ
.
In normal application R2 v alue is in the range of fe w Kohm, so t he R2 x I
DJ
product coul d not be
considered in the V
OUT
calculation; then the above expression becomes:
V
OUT=VREF
(1 + R2 / R1).
In order to have the better load regulation it is important to realize a good Kelvin connection of R1 and R2
resistors. In particular R1 c onnection must be rea lized very close to OUT and ADJ pin, while R2 grou nd
connection must be placed as near as possible to the negative Load pin. Ripple rejection can be improved
by introducing a 10µF electrolytic capacitor placed in parallel to the R2 resistor (s ee Fig.8).
