flows mostly into the load. Only a very common 10 µF 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.
• Low dropout voltage (1 V typ.)
• 2.85 V device performances are suitable for
SCSI-2 active termination
• Output current up to 800 mA
• Fixed output voltage of: 1.2 V, 1.8 V, 2.5 V,
3.3 V, 5.0 V
• Adjustable version availability (V
• Internal current and thermal limit
• Available in ± 1 % (at 25 °C) and 2 % in full
temperature range
• Supply voltage rejection: 75 dB (typ.)

Description
The LD1117 is a low drop voltage regulator able to provide up to 800 mA of output current, available even in adjustable version (V
1.25 V). Concerning fixed versions, are offered the following output voltages: 1.2 V, 1.8 V, 2.5 V,
2.85 V, 3.3 V and 5.0 V. The device is supplied in: SOT-223, DPAK, SO-8 and TO-220. The SOT­223 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

LD1117 adjustable: application note LD1117
7 LD1117 adjustable: application note
The LD1117 adjustable has a thermal stabilized 1.25 ± 0.012 V reference voltage between the OUT and ADJ pins. I
R
is normally fixed to 120 Ω. From Figure 9 we obtain:
1
V
OUT
= V
REF
+ R2 (I
ADJ
In normal application R be considered in the V
V
OUT
= V
(1 + R2 / R1).
REF
is 60 µA typ. (120 µA max.) and ΔI
ADJ
+IR1) = V
value is in the range of few kΩ, so the R2 x I
2
calculation; then the above expression becomes:
OUT
REF
+ R2 (I
ADJ
+V
REF
/R1) = V
In order to have the better load regulation it is important to realize a good Kelvin connection of R
and R2 resistors. In particul ar R1 connection must be realized very close to OUT and
1
ADJ pin, while R
ground connection must be placed as near as possible to the negative
2
Load pin. Ripple rejection can be improved by introducing a 10 µF electrolytic capacitor placed in parallel to the R
resistor (see Figure 10).
