Description

LM1086CSX-3.3 IC Integrated Circuits

Tutorial: How to use LM1086CSX-3.3

The LM1086CSX-3.3 is a DC-DC regulated voltage converter to stabilize the voltage at 3.3V. Useful for powering components sensitive to precise voltages in Arduino projects.

What you need

• LM1086CSX-3.3
• 10kΩ Resistor
• 10µF Capacitor
• 0.1µF Capacitor

Steps

1. Check the power supply voltage (VIN) must be at least 4.5V.
2. Connect VIN to +5V of the Arduino.
3. Connect the GND of the LM1086 to the GND of the Arduino.
4. Connect pin 2 (ADJ) to a 10kΩ resistor.
5. Power the 10kΩ resistor to GND.
6. Connect pin 3 (OUT) to pin 5V of another component.
7. Connect pin 1 (GND) to the GND of the component.
8. Check the datasheet for the correct configuration of capacitors
