The LM78L05ATA is a fixed 5V linear regulator delivering up to 100mA in a compact TO-92-3 package. With a low 1.7V dropout at 40mA and 6mA quiescent current, it offers efficient power conversion for battery-operated and embedded systems. Its 49dB PSRR at 120Hz ensures stable output in ripple-prone environments.
- Stable 5V output with 49dB PSRR – reduces power supply noise for sensitive circuits.
- Low 6mA quiescent current – ideal for battery-powered applications.
- Compact TO-92-3 package – fits space-constrained PCB designs.
- 100mA output capability – sufficient for small MCUs and analog ICs.
