The L79L05ACD13TR from STMicroelectronics is a fixed -5V negative voltage regulator capable of delivering 100mA. With a quiescent current of 5.5mA and PSRR of 49dB at 120Hz, it provides reliable negative rail generation for dual-supply systems. The 8-SOIC package ensures easy integration, while internal protections handle overcurrent and overtemperature conditions.
- Negative Output Capability: Specifically designed for -5V rails, essential for bipolar circuits.
- Compact SOIC-8: Saves board space compared to larger TO-92 alternatives.
- Built-in Protections: Short-circuit and thermal shutdown enhance system reliability.
- Low Noise Operation: 49dB PSRR filters input ripple effectively.
