LD1117S33TR Overview
The LD1117S33TR is a low-drop positive voltage regulator that is both adjustable and fixed. It can deliver up to 800 mA of output current and is even offered in an alterable version (VREF = 1.25 V).With the other standard, the adjustable LD1117S33TR is pin-to-pin compatible. Better drop and tolerance results are maintained via adjustable voltage regulators.

LD1117S33TR Method of Application
The LD1117S33TR is fairly easy to operate. If the voltage regulator is fixed, all that has to be done is power the IC with the Vin pin and get the output with the Vout pin. The Adj/Ground pin is grounded in this situation and only functions as a ground pin. To remove noise, a capacitor can also be placed to the output side.
Two external resistors are needed to calculate the output voltage of an adjustable type voltage regulator. The resistors R1 and R2 define the output voltage of the regulator in the reference circuit schematic that is displayed below. If more improvement is required, CAdj, an optional component, can be employed to enhance ripple rejection. The input and output noise is filtered using the other two capacitors. Information on the application circuit and other significant parameters can be found in the datasheet linked below.
