Hello, my first question is about the circuitry involved in one voltage regulator. I have an AMS1117 3V regulator, and I need to know how to hook it up. My supply voltage is 5V, the regulator has 3 pins. VIN, VOUT, and GROUND. This is how I have it connected in the circuit:
Ground - Ground
VIN - 5V+
Vout - accelerometer VS
I've seen many schematics using voltage regulators, that implement capacitors, a diode, and resistors. Do I need to consider any of this to make my regulator work efficiently? As of now, it seems to be dropping the voltage to 3V, but if I increase the input voltage, the output voltage also increases.
Question 2: I have an ADXL335 accelerometer which is powered by the above mentioned regulator, and its analog X, Y, Z outputs are connected to the analog (ADC) input pins of a 16F684 microcontroller. Is this correct, or do I need to add any capacitors / resistors / amplifiers between the analog output of the accelerometer, and the input pins of the microcontroller?
Any help is great help, thanks in advance!
