The AS78L05ZTR-E1 from Diodes Incorporated is a classic 100mA fixed 5V linear regulator in a TO-92 package. It offers a typical dropout of 1.8V and quiescent current of 5.5mA, making it a robust choice for general-purpose voltage regulation. With 62dB ripple rejection at 120Hz, it effectively filters AC line noise. This regulator includes internal current limiting and thermal shutdown for reliable operation in industrial and consumer applications.
- Proven Reliability: Industry-standard 78L05 pinout and performance, widely used for decades.
- Thermal Protection: Internal thermal shutdown prevents damage from overload.
- Low Noise: 62dB PSRR at 120Hz reduces mains hum in audio circuits.
- Cost-Effective: Simple TO-92 package and minimal external components reduce BOM cost.
