LM1117 Voltage Regulator – Low Dropout (LDO) Linear Regulator
20.00 EGP
The LM1117 is a popular low dropout linear voltage regulator (LDO) designed to provide a stable output voltage with a low input-to-output voltage difference. It is available in fixed output versions (e.g. 3.3V, 5V) or adjustable, making it ideal for powering microcontrollers, sensors, and digital ICs from a variety of sources.
