The MC78L05F-TP-HF from MCC is a fixed 5V low dropout linear regulator designed for space-constrained applications. It delivers up to 100mA of output current with a dropout voltage of just 1.7V at 40mA. The device features a low quiescent current of 5.5mA and excellent ripple rejection of 80dB at 120Hz, ensuring clean, stable power for sensitive electronics. Housed in a compact SOT-89 package, it is ideal for battery-powered devices, sensor interfaces, and microcontroller power supplies.
- Stable 5V Output: Fixed 5V regulation ensures consistent performance for logic circuits and microcontrollers without external resistor networks.
- High Ripple Rejection: 80dB PSRR at 120Hz effectively filters AC mains noise, providing clean power for analog and mixed-signal circuits.
- Low Dropout Voltage: 1.7V dropout at 40mA allows operation from lower input voltages, improving efficiency in battery-powered designs.
- Compact SOT-89 Package: Small footprint saves PCB space, ideal for miniaturized portable electronics.
Microcontroller Power Supply
Provide a stable 5V rail for 8-bit and 16-bit microcontrollers in embedded systems. The 100mA output is sufficient for the MCU core and basic peripherals, while the 80dB PSRR at 120Hz effectively filters mains ripple.
Sensor Interface Circuits
Power analog sensor front-ends that require a clean 5V supply. The low output noise and high power supply rejection ratio (80dB at 120Hz) minimize interference on sensitive analog measurements.
Battery-Powered Devices
Regulate battery voltage to a stable 5V for portable instruments. The low dropout of 1.7V allows operation from a 6V battery down to near 6.7V, maximizing battery utilization.
Logic Level Translation
Create a dedicated 5V logic supply for interfacing with TTL-compatible devices. The fixed output ensures consistent logic high levels, reducing communication errors.
Reference Voltage Source
Use as a simple, cost-effective 5V reference for comparators and ADC circuits. The fixed output and internal protection features provide a reliable reference point.
Industrial Control I/O
Power isolated digital input/output stages in PLCs and industrial controllers. The SOT-89 package and 100mA capability suit compact I/O modules.
