FULL TEMPERATURE RANGE
SUPPLY VOLTAGE REJECTION: 75dB (TYP.)
DESCRIPTION
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
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 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.

LD1117 ADJUSTABLE: APPLICATION NOTE
The LD1117 ADJUSTABLE has a thermal stabilized 1.25±0.012V reference voltage between the OUT
and ADJ pins. IADJ is 60µA typ. (120µA max.) and ∆IADJ is 1µA typ. (5µA max.).
R1 is normally fixed to 120Ω. From figure 7 we obtain:
VOUT = VREF + R2 (IADJ +IR1) = VREF + R2 (IADJ +VREF /R1) = VREF (1 + R2 / R1) + R2 x IADJ.
In normal application R2 value is in the range of few Kohm, so the R2 x IDJ product could not be
considered in the VOUT calculation; then the above expression becomes:
VOUT = 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 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).
