The L7805ABD2T-TR is a fixed 5V linear voltage regulator from STMicroelectronics, capable of delivering up to 1.5A of output current. Housed in a D2PAK package, it offers a typical dropout voltage of 2V at 1A and a quiescent current of 6mA. With a power supply rejection ratio of 68dB at 120Hz, it effectively filters input noise, making it suitable for a wide range of industrial and consumer applications.
- High Output Current: 1.5A capability supports power-hungry loads without additional pass transistors.
- Excellent Noise Rejection: 68dB PSRR at 120Hz ensures clean output for audio and precision circuits.
- Robust Thermal Performance: D2PAK package dissipates heat efficiently, enabling sustained operation at high currents.
- Low Quiescent Current: 6mA idle current reduces power waste in always-on applications.
