# 7805 (Component) ## Description 5V Positive Fixed TO-220 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators RoHS The 7805 is a fixed positive linear voltage regulator IC that provides a regulated +5 V DC output from a higher DC input voltage. It belongs to the widely used 78xx series of voltage regulators, where "05" indicates the 5 V output voltage. The device is commonly used in power supplies for microcontrollers, digital logic circuits, sensors, communication modules, and other electronic systems requiring a stable 5 V supply. It typically requires only a few external capacitors for reliable operation and includes built-in protection features for enhanced robustness. Key Features Fixed 5 V regulated output voltage Output current capability up to 1 A to 1.5 A (depending on manufacturer, package, and thermal conditions) Wide input voltage range (typically up to 35 V maximum) Internal thermal overload protection Internal short-circuit current limiting Safe Operating Area (SOA) protection Requires minimal external components Good line and load regulation Available in common packages such as TO-220, TO-263, and others Suitable for embedded systems, industrial controls, instrumentation, and general-purpose power supplies Typical Applications 12 V to 5 V power conversion Microcontroller and development board power supplies Embedded and IoT devices Digital logic circuits (TTL/CMOS) Sensor and communication module power regulation Educational and hobby electronics projects #CommonPartsLibrary #IntegratedCircuit #PowerManagement ## Component Details - **Owner:** lcsc - **Created:** 10/17/2024 - **Last Updated:** 6/2/2026 - **Visibility:** Public - **Part Type:** Linear Voltage Regulators (LDO) - **Package or Case Code:** TO-220-3_L10.0-W4.5-P2.54-L - **Compliance:** RoHS - **Manufacturer Part Number:** 7805 - **LCSC Part Number:** C2984683 - **Manufacturer Name:** Collective Semiconductor Technology - **JLCPCB Part Class:** Extended Part - **Symbol Style:** parametric-v1 - **Datasheet URL:** https://www.lcsc.com/datasheet/C2984683.pdf?spm=wm.sxq.inf.ggs&lcsc_vid=T1kIXgFeT1NaU1RXQFBbUlUHT1cKU1NXFVBeX1VSTlAxVlNeR1VeUlFeQFNfXjsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **License:** https://creativecommons.org/licenses/by/4.0/ - **Used in:** 197 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
