DESCRIPTION
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.
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.
Laser trimming assures excellent output voltage accuracy
without adjustment. An NPN output stage allows output
stage drive to contribute to the load current for maximum
efficiency.

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.

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
0.5Ω.

Figure 1. Fixed-Voltage Model—Basic
Connections
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.
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 s i n k o r e x c essive pow er dissipa t ion. The
power dissipation is equal to:
PD = (VIN – VOUT) IOUT
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.

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.
3−Lead DDPAK(1)
NOTE: (1) For improved thermal performance increase
footprint area. See Figure 4 (Thermal Resistance vs
Circuit Board 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 t h e
leads should be made as large as practical. The mounting
tab of both packages is electrically connected to VOUT.

Figure 5. SOT-223 Circuit Board Layout Example
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.
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
maximum power dissipation at a given ambient
temperature, as shown in Figure 6.

SOLDERING METHODS
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.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
