LM1117-800mA Low Dropout Linear Regulator
The LM1117 is a series of low dropout regulators with a 1.2V dropout at a load current of 800mA. It has the same pinout as National Semiconductor's industry standard LM317. The LM1117 is an adjustable version, which can set the output voltage from 1.25V to 13.8V with only two external resistors. Besides, it can also work at five constant voltages, 1.8V, 2.5V, 2.85V, 3.3V and 5V. The LM1117 provides current limit and thermal shutdown. Its circuitry includes a Zener trimmed bandgap reference to ensure output voltage accuracy to within ±1%. The LM1117 series is available in the LLP, TO-263, SOT-223, TO-220 and TO-252 D-PAK packages. A 10µF minimum tantalum capacitor is required at the output to improve transient response and stability.
