The LM78L05TA from TAEJIN is a fixed positive linear regulator providing 5V output at up to 100mA. Housed in a TO-92-3 package, it features a dropout voltage of 1.7V at 40mA and a quiescent current of 6mA. With a PSRR of 49dB at 120Hz, it delivers stable 5V power for microcontrollers, sensors, and logic circuits. Its three-terminal design requires minimal external components.
- Fixed 5V Output: Standard voltage for TTL logic and many MCUs.
- 100mA Output Current: Suitable for small digital and analog loads.
- TO-92-3 Package: Compact through-hole package for easy prototyping.
- Good PSRR (49dB @ 120Hz): Filters mains ripple for clean DC output.
Microcontroller Power Supply
Many 8-bit and 16-bit microcontrollers operate at 5V. The LM78L05TA provides a stable 5V rail from a higher input voltage (e.g., 9V or 12V), ensuring reliable operation of MCUs in embedded systems.
Sensor Interface Circuits
Analog sensors like temperature and pressure transducers often require a 5V excitation or reference. The LM78L05TA delivers a clean 5V supply, improving measurement accuracy in industrial and consumer applications.
Logic Level Conversion
When interfacing 5V logic with 3.3V systems, the LM78L05TA can power level-shifting circuits, ensuring proper voltage compatibility in mixed-voltage designs.
Relay and Solenoid Drivers
Electromechanical devices like relays need a regulated 5V supply for their coils. The LM78L05TA can power these loads, providing consistent actuation in automation and control systems.
Battery Charger Reference
Simple battery chargers use a 5V reference for voltage monitoring. The LM78L05TA provides a stable reference, enabling accurate charge termination in portable devices.
Audio Preamplifier Supply
Low-noise audio preamps often run from 5V. The LM78L05TA's PSRR of 49dB at 120Hz helps reject power supply hum, delivering clean audio in consumer electronics.
