What are the features of the lm1117 IC?
The features of the LM1117 are as follows: Linear voltage regulator having a minimum drop out voltage of 1.1V. Generate fixed voltages of 1.8, 2.5, 3.3 and 5 volts. Range for variable voltage is 1.25V to 13.8V. Maximum input voltage for this IC is 20V. Line regulation of 0.1% max and load regulation of 0.2% max. The output current is 800mA.
What is the dropout voltage of the lm1117?
3 Description The LM1117 is a low dropout voltage regulator with a dropout of1.2 V at 800 mA 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.
How does the lm1117 adjustable voltage regulator work?
The adjustable regulator works with a similar circuit as the fixed unit. In addition to the capacitors, the adjustable LM1117 uses two resistors to set the output voltage. It is important to note that the adjustable unit uses one 10uf capacitor and one 100uf capacitor. To set the voltage, two resistors are used.
What kind of capacitor does the lm1117 use?
The data sheet specifies 10uf tantalum capacitors but I’ve found that polarized aluminum capacitors work just as well. To set up, attach one capacitor from the output pin of the LM1117 to the ground pin of the LM1117. Next, do the same going from the input pin to the ground pin. These capacitors are polarized.
