LM 1117 Fixed Voltage Regulator. Component Guide 6

LM1117-Voltage-regulatorLM 1117 is the tiny Fixed Voltage Regulator that drops 5 Volt DC to fixed 3.3 V DC. It can output maximum 800 mA. Like 78XX series Voltage regulators, LM1117 is also a three pin device with In, Out and Ground pins. Ideal Voltage regulator for Microcontroller and Arduino Projects that needs fixed 3.3 volts.

Only two capacitors are needed with LM 1117 to make a low voltage regulator power supply. Input can be 5 Volt DC up to 1 Amps which can be derived from the USB port also.
