The 78M05A is a fixed 5V linear voltage regulator delivering up to 500mA of output current. Packaged in a TO-252 (DPAK), it features a dropout voltage of 2V at 500mA and a quiescent current of 6 mA. With an 80dB power supply rejection ratio at 120Hz, it provides excellent filtering of AC ripple, making it ideal for consumer electronics, automotive modules, and battery-powered devices.
- High Ripple Rejection: 80dB PSRR at 120Hz ensures a clean, stable output for sensitive electronics.
- Compact TO-252 Package: Surface-mount design saves PCB space while providing adequate thermal dissipation.
- Low Quiescent Current: 6 mA quiescent current enhances efficiency in battery-operated applications.
- Reliable Protection: Built-in thermal shutdown and safe-area protection safeguard the regulator and load.
