3 The LM1117 features very low quiescent current and very low dropout VOLTAGE of 1V at a full load and lower as output current decreases. LM1117 is available as an adjustable or fixed , , , , , , and output voltages. The LM1117 is offered in a 3-pin surface mount package SOT-223, TO-252 & SOT-89. The output capacitor of 10uF or larger is needed for output stability of LM1117 as required by most of the other REGULATOR circuits. MLCC output capacitors are applicable with and Absolute Maximum Ratings (TA = 25 C, unless otherwise specified) CHARACTERISTIC SYMBOL MIN.
