Fairchild/ON Semiconductor LM7809CT

LM7809CT Overview
Moisture Sensitivity Level (MSL) is a measure of how sensitive a component is to moisture, with level 1 being the least sensitive, or "unlimited." This means that the component can be exposed to moisture without any adverse effects. The Terminal Pitch, or distance between the terminals, is 2.54mm, making it a standard size for easy use. The Output Type is Fixed, meaning that the output voltage will remain constant regardless of any changes in input voltage or load. The Nominal Supply Current is 5mA, indicating the amount of current the component requires to function properly. The Accuracy is 4%, meaning that the component's output voltage will be within 4% of the expected value. The Min Input Voltage is 11.5V, which is the minimum voltage required for the component to function. The component also has a PSRR (Power Supply Rejection Ratio) of 71dB at 120Hz, indicating its ability to reject any noise from the power supply. The Voltage Tolerance-Max is 4.4%, meaning that the output voltage can deviate by up to 4.4% from the nominal value. The Nominal Output Voltage is 9V, the expected output voltage of the component. Lastly, the component is not radiation hardened, meaning it is not designed to withstand exposure to high levels of radiation. Overall, the MSL level, terminal pitch, output type, supply current, accuracy, input voltage, PSRR, voltage tolerance, output voltage, and radiation hardening all play important roles in the functionality and performance of this component.
