Description
LM7809 is a fixed-voltage integrated-circuit voltage regulator designed for a wide range of applications. The L7809 voltage regulator provides 9V Positive voltage as output and can provide local on-card regulation, eliminating the distribution problems associated with single-point regulation. Although designed primarily as a fixed voltage regulator, but it can be used with external components to obtain adjustable voltage.
Features
- Fixed 9V Output: Delivers a stable +9V DC output.
- High Output Current: Can provide a continuous output current up to 1.5A.
- High Input Voltage Capability: Accepts an input voltage of up to 35V DC.
- Built-in Protections: Features internal protection against overheating (thermal shut-down) and short-circuit conditions.
- Dropout Voltage: Requires an input voltage at least 2V higher than the output voltage to ensure stable regulation.
- Internal Current Limiting: Prevents damage from excessive current by limiting the output current.
- Safe Operating Area (SOA) Protection: Protects against potential damage from operating outside of the device's safe design limits.
- No External Components Required: Can function as a standalone unit for basic regulation, simplifying circuit design.
- Local Regulation: Provides voltage regulation directly at the circuit board where it is needed, reducing issues with single-point regulation.
- Power Management: Acts as a power management component, stabilizing voltage levels for sensitive electronic devices.
