The L7805CDT-TR from STMicroelectronics is a classic 5V positive voltage regulator capable of delivering 1.5A. With a typical dropout of 2V and built-in thermal overload and short-circuit protection, it offers a rugged, reliable solution for a wide range of applications. The DPAK package allows efficient heat dissipation, making it suitable for both consumer and industrial power supplies.
- High Output Current: 1.5A capability supports power-hungry loads like motors and multiple ICs.
- Built-in Protection: Thermal shutdown and short-circuit protection ensure safe operation under fault conditions.
- Low Noise: 62dB PSRR at 120Hz reduces ripple from rectified AC, ideal for audio and precision circuits.
- Industry Standard: Pin-compatible with common 7805 regulators, simplifying replacement and design.
General-Purpose 5V Power Supply
With 1.5A output capability, the L7805CDT-TR is a robust choice for powering logic circuits, relays, and small motors in hobbyist and industrial projects.
Microcontroller Power Rails
Provide a stable 5V rail for Arduino-compatible boards and 5V MCUs, with enough headroom for peripheral sensors and displays.
Audio Equipment Biasing
The 62dB PSRR at 120Hz helps reduce hum from rectified AC in audio preamplifiers and mixers.
Automotive Aftermarket Accessories
Regulate vehicle battery voltage (12V) down to 5V for dashcams, GPS trackers, and USB chargers, with thermal shutdown protection.
Industrial Control Panels
Use as a local 5V source for PLC I/O modules, ensuring reliable operation in noisy factory environments.
Bench Power Supply Output Stage
As a post-regulator after a variable supply, it provides a clean, fixed 5V for testing TTL logic circuits.
