FEATURES
DESCRIPTION
The LM1117-N is a series of low dropout voltage
2
Available in 1.8V, 2.5V, 2.85V, 3.3V, 5V, and
regulators with a dropout of 1.2V at 800mA of load
Adjustable Versions
current.
It
has
the
same
pin-out
as
Texas
Space Saving SOT-223 and WSON Packages
Instruments' industry standard LM317.
Current Limiting and Thermal Protection
The LM1117-N is available in an adjustable version,
Output Current 800mA
which can set the output voltage from 1.25V to 13.8V
with only two external resistors. In addition, it is also
Line Regulation 0.2% (Max)
available in five fixed voltages, 1.8V, 2.5V, 2.85V,
Load Regulation 0.4% (Max)
3.3V, and 5V.
Temperature Range
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%.
APPLICATIONS
The LM1117-N series is available in WSON, PFM,
2.85V Model for SCSI-2 Active Termination
SOT-223, TO-220, and TO-263 DDPAK packages. A
minimum of 10µF tantalum capacitor is required at
Post Regulator for Switching DC/DC Converter
