The L7805CP is a fixed 5V linear voltage regulator from STMicroelectronics, capable of delivering up to 1.5A of output current. With a typical dropout voltage of 2V at 1A and a quiescent current of 8 mA, it offers efficient and stable power conversion for a wide range of applications. The TO-220FP package ensures easy mounting and effective heat dissipation, making it a reliable choice for both prototyping and production.
- High Output Current: Supports up to 1.5A, suitable for powering multiple components or higher-power loads.
- Low Quiescent Current: 8 mA quiescent current minimizes power loss, improving efficiency in battery-operated devices.
- Excellent Ripple Rejection: 62dB PSRR at 120Hz ensures clean, stable output for sensitive analog circuits.
- Thermal and Short-Circuit Protection: Built-in safety features protect the regulator and connected circuitry from damage.
5V Logic Power Supply
Provides a stable 5V rail for microcontrollers, digital ICs, and logic circuits, with up to 1.5A capacity for moderate loads.
Battery-Powered Devices
Regulates battery voltage (e.g., 9V or 12V) down to a clean 5V, extending battery life with its low quiescent current of 8 mA.
Audio Equipment
Delivers low-noise 5V power for audio codecs and amplifiers, leveraging 62dB PSRR at 120Hz to reject mains hum.
