The L78L05ACD13TR from STMicroelectronics is a fixed 5V, 100mA positive voltage regulator in an 8-SOIC package. It offers a typical quiescent current of 5.5 mA and a PSRR of 49dB at 120Hz, providing stable and clean power for logic and analog circuits. This three-terminal regulator is a robust and economical solution for a wide range of low-power applications.
- Proven Reliability: Based on the industry-standard 78L05 architecture, ensuring long-term availability and design familiarity.
- Mains Ripple Rejection: 49dB PSRR at 120Hz effectively filters AC line noise, ideal for audio and measurement circuits.
- Simple Integration: Requires minimal external components, simplifying PCB design and reducing BOM cost.
- Wide Availability: Standard 8-SOIC package and common specifications make it easy to source from multiple distributors.
General-Purpose 5V Logic Supply
Provides a stable 5V rail for TTL logic ICs, microcontrollers, and digital circuits in industrial control systems, with 100mA capacity for small logic loads.
Analog Sensor Conditioning
With 49dB PSRR at 120Hz, it effectively filters mains-frequency ripple, making it suitable for powering op-amps and sensor bridges in precision measurement equipment.
Home Appliance Control Boards
Reliable and cost-effective solution for powering control electronics in appliances like washing machines and microwaves, where 5V logic and interface circuits are common.
