SNOS412M –FEBRUARY 2000–REVISED MARCH 2013
The LM1117-N is a series of low dropout voltage
Available in 1.8V, 2.5V, 2.85V, 3.3V, 5V, and
regulators with a dropout of 1.2V at 800mA of load
current. It has the same pin-out as Texas
Instruments' industry standard LM317.
Space Saving SOT-223 and WSON Packages
Current Limiting and Thermal Protection
Output Current 800mA
The LM1117-N is available in an adjustable version,
which can set the output voltage from 1.25V to 13.8V
with only two external resistors. In addition, it is also
available in five fixed voltages, 1.8V, 2.5V, 2.85V,
3.3V, and 5V.
Line Regulation 0.2% (Max)
Load Regulation 0.4% (Max)
The LM1117-N offers current limiting and thermal
LM1117-N: 0°C to 125°C
shutdown. Its circuit includes
a zener trimmed
LM1117I: −40°C to 125°C
bandgap reference to assure output voltage accuracy
to within ±1%.
The LM1117-N series is available in WSON, PFM,
SOT-223, TO-220, and TO-263 DDPAK packages. A
minimum of 10µF tantalum capacitor is required at
the output to improve the transient response and
