Voltage Regulator – 3.3V


Availability: In Stock


SKU: ELC-054 Manufacturer: STMicroelectronics Mfg Part Number: LD1117V33C Categories: , Tags: ,


A voltage regulator is used to reduce and regulate the voltage of a circuit. Components such as sensors and microcontrollers typically need a very specific regulated voltage to ensure accurate readings or stable operation. These simple low drop out regulators are perfect for that job.

This specific regulator will convert anything between 4.75VDC and 15VDC to a regulated 3.3VDC. These do not technically require any additional circuitry to work; when 4.75V – 15V is applied to the input pin the output pin will have 3.3V out. We do recommend using a few capacitors with these to ensure stability.

Please note: As the load increases towards the maximum rating on these regulators they do tend to get quite warm. The temperature increase is also proportional to the input voltage; the higher the input voltage the warmer this regulator will run. Basically, the higher the input voltage, the lower the sustainable output current will be. Heatsinks are always a good idea with these chips!
