FEATURES  
DESCRIPTION  
D
FIXED AND ADJUSTABLE VERSIONS  
2.85V MODEL FOR SCSI-2 ACTIVE  
TERMINATION  
The REG1117 is a family of easy-to-use three-terminal  
voltage regulators. The family includes a variety of fixed-  
and adjustable-voltage versions, two currents (800mA and  
1A) and two package types (SOT-223 and DDPAK). See  
the chart below for available options.  
D
D
OUTPUT CURRENT:  
REG1117: 800mA max  
Output voltage of the adjustable versions is set with two  
external resistors. The REG1117 low dropout voltage  
allows its use with as little as 1V input-output voltage  
differential.  
REG1117A: 1A max  
OUTPUT TOLERANCE: + 1% max  
DROPOUT VOLTAGE:  
REG1117: 1.2V max at I = 800mA  
D

O
Laser trimming assures excellent output voltage accuracy  
without adjustment. An NPN output stage allows output

Figure 2 shows a hookup diagram for the adjustable  
voltage model. Resistor values are shown for some  
commonly-used output voltages. Values for other voltages  
can be calculated from the equation shown in Figure 2. For  
best load regulation, connect R1 close to the output pin and  
R2 close to the ground side of the load as shown.  
APPLICATIONS INFORMATION  
Figure 1 shows the basic hookup diagram for fixed-voltage  
models. All models require an output capacitor for proper  
operation, and for improving high-frequency load  
regulation; a 10µF tantalum capacitor is recommended.  
Aluminum electrolytic types of 50µF or greater can also be  
used. A high-quality capacitor should be used to assure  
that the ESR (Effective Series Resistance) is less than  
0.5.  
THERMAL CONSIDERATIONS  
The REG1117 has current limit and thermal shutdown  
circuits that protect it from overload. The thermal shutdown  
activates at approximately TJ = 165°C. For continuous  
operation, however, the junction temperature should not  
be allowed to exceed 125°C. Any tendency to activate the  
thermal shutdown in normal use is an indication of an  
inadequate heat sink or excessive power dissipation. The  
power dissipation is equal to:

The junction temperature can be calculated by:  
TJ = TA + PD (qJA)  
where TA is the ambient temperature, and qJA is the  
junction-to-ambient thermal resistance.

SBVS001D − OCTOBER 1992 − REVISED JULY 2004  
A simple experiment will determine whether the maximum  
recommended junction temperature is exceeded in an  
actual circuit board and mounting configuration: Increase  
the ambient temperature above that expected in normal  
operation until the device’s thermal shutdown is activated.  
If this occurs at more than 40°C above the maximum  
expected ambient temperature, then TJ will be less than  
125°C during normal operation.  
The internal protection circuitry of the REG1117 was  
designed to protect against overload conditions. It was not  
intended to replace proper heat sinking. Continuously  
running the REG1117 into thermal shutdown will degrade  
reliability.  
LAYOUT CONSIDERATIONS  
The DDPAK (REG1117F-3.3 and REG1117FA) is a  
surface-mount power package that has excellent thermal  
characteristics. For best thermal performance, the  
mounting tab should be soldered directly to a circuit board  
copper area, as shown in Figure 3. Increasing the copper  
area improves heat dissipation. Figure 4 shows typical  
thermal resistance from junction-to-ambient as a function  
of the copper area.

The SOT-223 package derives heat sinking from  
conduction through its copper leads, especially the large  
mounting tab. These must be soldered to a circuit board  
with a substantial amount of copper remaining, as shown  
in Figure 5. Circuit board traces connecting the tab and the  
leads should be made as large as practical. The mounting

SOLDERING METHODS  
Other nearby circuit traces, including those on the back  
side of the circuit board, help conduct heat away from the  
device, even though they may not be electrically  
connected. Make all nearby copper traces as wide as  
possible and leave only narrow gaps between traces.  
Both REG1117 packages are suitable for infrared reflow  
and vapor-phase reflow soldering techniques. The high  
rate of temperature change that occurs with wave  
soldering or hand soldering can damage the REG1117.  
Table 1 shows approximate values of qJA for various circuit  
board and copper areas for the SOT-223 package. Nearby  
heat dissipating components, circuit board mounting  
conditions, and ventilation can dramatically affect the  
actual qJA. Proper heat sinking significantly increases the
