L7809 is used to regulate the output voltage at both ends of the device with a constant voltage drop. The switching regulators operated by switching between different voltage levels are different, and linear regulators dissipate excess power as heat to maintain a stable output voltage.

Features

Lumimax Optoelectronic Technology L7809 has 1.5A output current, which can meet the current driving needs of high loads. It also has control features and Over Current, Over Temperature, Short Circuit protection features, making it easy to turn on or off the chip and protecting it from damage in abnormal situations. The maximum input voltage is 35V, the maximum output voltage is , and the Voltage Output (Min/Fixed) is 9V. The wide voltage range can adapt to electronic products under different power conditions. Voltage Dropout (Max) is 2V @ 1A, which has good voltage regulation effect. The output type of L7809 is Fixed, which can finely control the voltage, 1.5A output current, and 8 mA Quiet (Iq) Current. Due to the low internal static current, it reduces power consumption and can meet the needs of small and medium-sized electronic products. The maximum current support is . This IC adopts the TO-220-3 package and has 1 regulators and Positive output configurations, which can effectively suppress the impact of load changes on output voltage and provide stable voltage. Its PSRR is 55dB (120Hz) and belongs to the L78 series.

L7809 Manufacturer TO-220 Through Hole Packaging process, with advantages such as small size and fast heat dissipation, and Bulk packaging method, improves product reliability and consistency, making batch application and storage more convenient.
