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 t yp e is ideal for
SCSI-2 lines active termination. The device is
supplied in: SOT-223, DPAK, SO-8 and TO-220.
The SOT-223 and DPAK surfa ce 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 comm on
10µF minimum capacitor is needed for stability.
On chip trimming a llows 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 a thermal

the OUT and ADJ pins. I

In normal application R2 value is in the range of

OUT
= V
(1 + R2 / R1).
REF
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 con nection
must be realized very close to OUT and A DJ pin,
while R2 ground connection must be placed as
near as poss ible to the ne gative Loa d pin. Rippl e
rejection can be improv ed by introducing a 10µF
electrolytic capacitor placed in parallel to the R2
resistor (see Fig. 12).
