Pinout
The LM809M3X-3.08 comes in a 3-pin SOT-23 package. The pin functions are as follows:
1. GND (Ground): This pin is connected to the ground of the system.
2. VCC (Power Supply): This pin is connected to the supply voltage that needs to be monitored.
3. RESET (Output): This active-low output pin provides the reset signal to the microprocessor. The RESET pin goes low when the supply voltage falls below the specified threshold (3.08V in this case) and stays low for a fixed period after the supply voltage exceeds the threshold to ensure a stable reset.
These 3 pins provide a simple yet effective solution for ensuring reliable operation of microprocessor systems by preventing erratic behavior during voltage fluctuations.
