800 mA Low-Dropout Linear
Regulator
LM1117
The LM1117 is a low dropout voltage regulator with a dropout of
1.2 V at 800 mA of load current. The LM1117 is available in an
adjustable version, which can set the output voltage from 1.25 to
13.8 V with only two external resistors. In addition, it is available in
five fixed voltages, 1.8 V, 2.5 V, 3.3 V, and 5 V.

The LM1117 offers current limiting and thermal shutdown. Its
circuit is trimmed to assure output voltage accuracy to within +/−1%.

APPLICATIONS INFORMATION
Introduction
Frequency compensation for the regulator is provided by
The LM1117 features a significant reduction in dropout
voltage along with enhanced output voltage accuracy and
temperature stability when compared to older industry
standard three−terminal adjustable regulators. These
devices contain output current limiting, safe operating area
compensation and thermal shutdown protection making
them designer friendly for powering numerous consumer
and industrial products. The LM1117 series is pin
compatible with the older LM317 and its derivative device
types.
capacitor C and its use is mandatory to ensure output
out
stability. A minimum capacitance value of 4.7 mF with an
equivalent series resistance (ESR) that is within the limits of
33 mW (typ) to 2.2 W is required. See Figures 12 and 13. The
capacitor type can be ceramic, tantalum, or aluminum
electrolytic as long as it meets the minimum capacitance
value and ESR limits over the circuit’s entire operating
temperature range. Higher values of output capacitance can
be used to enhance loop stability and transient response with
the additional benefit of reducing output noise.

The typical application circuits for the fixed and
adjustable output regulators are shown in Figures 23 and 24.
The adjustable devices are floating voltage regulators. They
develop and maintain the nominal 1.25 V reference voltage
between the output and adjust pins. The reference voltage is
programmed to a constant current source by resistor R1, and
this current flows through R2 to ground to set the output
voltage. The programmed current level is usually selected to
be greater than the specified 5.0 mA minimum that is

significantly lower and constant with respect to the
programmed load current, it generates a small output
voltage error that can usually be ignored. For the fixed
output devices R1 and R2 are included within the device and
The output ripple will increase linearly for fixed and
adjustable devices as the ratio of output voltage to the
reference voltage increases. For example, with a 12 V
regulator, the output ripple will increase by 12 V/1.25 V or
9.6 and the ripple rejection will decrease by 20 log of this
ratio or 19.6 dB. The loss of ripple rejection can be restored
to the values shown with the addition of bypass capacitor

sensitivity when powered from a complex source impedance

input bypass capacitor should be mounted with the shortest
possible track length directly across the regulator’s input
and ground terminals. A 10 mF ceramic or tantalum
capacitor should be adequate for most applications.

of R1 can be selected to provide the minimum required load

The second condition is that the ground end of R2 should be
connected directly to the load. This allows true Kelvin
sensing where the regulator compensates for the voltage
drop caused by wiring resistance RW −.

used in the typical regulator applications. The first path

Thermal Considerations
1N4001
This series contains an internal thermal limiting circuit
that is designed to protect the regulator in the event that the
maximum junction temperature is exceeded. When
activated, typically at 175°C, the regulator output switches
off and then back on as the die cools. As a result, if the device
is continuously operated in an overheated condition, the
output will appear to be oscillating. This feature provides
protection from a catastrophic device failure due to
accidental overheating. It is not intended to be used as a
substitute for proper heatsinking. The maximum device
power dissipation can be calculated by:

A combination of protection diodes D1 and D2 may be
required in the event that V is shorted to ground and C
is greater than 50 mF. The peak current capability stated for
the internal diodes are for a time of 100 ms with a junction
temperature of 25°C. These values may vary and are to be
used as a general guide.

The LM1117 series is capable of providing excellent load
regulation; but since these are three terminal devices, only
partial remote load sensing is possible. There are two
conditions that must be met to achieve the maximum
available load regulation performance. The first is that the
top side of programming resistor R1 should be connected as
close to the regulator case as practicable. This will minimize
the voltage drop caused by wiring resistance RW + from
appearing in series with reference voltage that is across R1.

changes made in the copper aspect ratio of the final layout,
adjacent heat sources, and air flow.

The 50 W resistor that is in series with the ground pin of the
upper regulator level shifts its output 300 mV higher than the
lower regulator. This keeps the lower regulator off until the
input source is removed.
