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 to 13.8 V with only two external resistors. In addition, it is available in five fixed voltages, 1.8 V, 2.5 V, 3.3 V, and 5 V.
(2) The maximum power dissipation is a function of TJ(max) , RθJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max)–TA)/RθJA. All numbers apply for packages soldered directly into a PCB.
A minimum of 10-µF tantalum capacitor is required at the output to improve the transient response and stability.

DESCRIPTION(X=Output Voltage=1.5V, 1.8V, 2.5V, 2.85V,
'3.0V, 3.3V, 5.0V, Adjustable=AD)The LM1117 is a low power positive-voltage regulator designed to meet 1A output current and complywith SCSI-II specifications with a fixed output voltage of 2.85V. This device is an excellent choice for usein battery-powered applications, as active terminators for the SCSI bus, and portable computers.The LM1117 features very low quiescent current and very low dropout voltage of 700mV at a full load and
lower as output current decreases. LM1117 is available as an adjustable or fixed 1.5V, 1.8V, 2.5V, 2.85V, 3.0V, 3.3V, and 5.0V output voltages.The LM1117 is offered in a 3-pin surface mount package SOT-223 & TO-263. The output capacitor of10㎌ or larger is needed for output stability of LM1117 as required by most of the other regulator circuits.
