DESCRIPTION
DPAK
SOT-223
SO-8
The LD1117 is a LOW DROP Voltage Regulator
able to provide up to 800mA of Output Current,
available even in adjustable version (Vref=1.25V).
Concerning fixed versions, are offered the
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
pass transistor. In fact in this case, unlike than
PNP one, the Quiescent Current flows mostly into
the load. Only a very common 10µF 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.

The LD1117 ADJUSTABLE has
stabilized 1.25±0.012V reference voltage between
the OUT and ADJ pins. I is 60µA typ. (120µA

OUT

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 connection
must be realized very close to OUT and ADJ pin,
while R2 ground 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 (see Fig.8).
ADJ

is 1µA typ. (5µA max.).
ADJ
R1 is normally fixed to 120Ω. From figure 7 we
obtain:

In normal application R2 value is in the range of
few kohm, so the R2 x I product could not be
