LM1117 SNOS412Q – FEBRUARY 2000 – REVISED JANUARY 2023 LM1117 800-mA, Low-Dropout Linear Regulator 1 Features For a newer drop-in alternative, see the TLV1117 For drop-in replacements in fixed output SOT-223 package configuration and improved functionality, see the TLV761 Available in 1.8 V, 2.5 V, 3.3 V, 5 V, and adjustable versions Space-saving SOT-223 and WSON packages Current limiting and thermal protection Output current: 800 mA Line regulation: 0.2% (maximum) Load regulation: 0.4% (maximum) Temperature range: – LM1117: 0°C to +125°C – LM1117I: –40°C to +125°C 2 Applications AC drive power stage modules Merchant network and server PSU Industrial AC/DC Ultrasound scanners Servo drive control modules 3 Description 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 V to 13.8 V with only two external resistors. In addition, the device 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. The circuit includes a Zener trimmed bandgap reference to assure output voltage accuracy to within ±1%. A minimum of 10-µF tantalum capacitor is required at the output to improve the transient response and stability.
