The L79L05ACUTR from STMicroelectronics is a fixed -5V negative linear regulator capable of delivering 100mA. It features a quiescent current of 5.5mA and PSRR of 49dB at 120Hz, making it suitable for dual-supply applications. The SOT-89-3 package offers a compact solution for generating negative rails in industrial and audio equipment. Internal protections include current limiting and thermal shutdown.
- Negative Rail Solution: Specifically designed for -5V generation, essential for bipolar circuits.
- Compact SOT-89: Smaller than traditional TO-92, saving PCB space.
- Thermal Protection: Built-in shutdown prevents overheating in fault conditions.
- Industry Standard: Pin-compatible with common 79L05 regulators for easy drop-in.
