LD1117 series
Low drop fixed and adjustable positive voltage regulators
Feature summary
■ Low dropout voltage (1V TYP.)
■ 2.85V Device performances are suitable for
SCSI-2 active termination
■ Output current up to 800 mA
DPAK
SO-8
■ Fixed output voltage of: 1.2V, 1.8V, 2.5V,
TO-220
2.85V, 3.0V, 3.3V, 5.0V
■ Adjustable version availability (Vrel=1.25V)
■ Internal current and thermal limit
■ Available in 1% (at 25°C) and 2% in full
SOT-223
temperature range
■ Supply voltage rejection: 75dB (typ.)
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.
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 and TO-220.

LD1117 Adjustable: Application note

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 120W. From figure 10 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 IADJ 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. 11).
