The LM78M05RS is a classic fixed 5V positive voltage regulator from TAEJIN, capable of delivering up to 500mA. Housed in a TO-252-3 (DPAK) package, it offers a simple and reliable solution for creating a stable 5V power rail. With a quiescent current of 6mA and a dropout voltage of 2.2V at 350mA, it is a robust choice for many general-purpose applications.
- Higher Output Current: 500mA capability supports a wider range of loads compared to typical 150mA LDOs.
- Robust Package: TO-252-3 (DPAK) package offers good thermal performance for power dissipation.
- Simple Integration: Fixed 5V output requires minimal external components for basic operation.
- Proven Technology: Based on the industry-standard 78M05 topology, ensuring reliable and predictable performance.
