The 78L05-150 from UMW is a fixed 5V linear regulator delivering up to 150mA in a compact SOT-89 package. With a dropout of 1.7V at 40mA and quiescent current of 5.5mA, it offers simple, reliable regulation for low-power applications. Its 49dB PSRR at 120Hz ensures clean output for sensitive circuits.
- Stable 5V output: Fixed voltage eliminates external resistor network, simplifying design.
- Compact SOT-89 package: Saves PCB space for space-constrained designs.
- Low quiescent current (5.5mA): Reduces power loss in always-on applications.
- Good ripple rejection (49dB at 120Hz): Minimizes mains hum in audio and instrumentation.
Microcontroller Power Supply
Provides a stable 5V rail for MCUs and digital logic from a higher unregulated input, with 150mA capacity sufficient for most small controllers and sensors.
Battery-Powered Devices
With 5.5mA quiescent current, it is suitable for always-on circuits in battery equipment where moderate efficiency is acceptable.
Reference Voltage Source
The fixed 5V output with 49dB PSRR at 120Hz makes it a reliable reference for analog circuits and ADC inputs.
Industrial Sensor Interfaces
Regulates 5V for op-amps and signal conditioning circuits, rejecting mains-frequency noise.
Consumer Audio Equipment
Provides clean 5V supply for audio codecs and preamplifiers, reducing hum and ripple.
Automotive Accessory Power
Converts vehicle battery voltage to 5V for dashcams or USB adapters, within current limits.
