5V Voltage Regulator
Build a stable 5V DC power supply using the LM340 voltage regulator. Ideal for microcontroller circuits and small electronics projects.
5v fixed voltage regulator
LM340 is a regulated voltage (regulated voltage = 5V) transistor that maintains a stable supply of power to the electronic components. It is usually applied in embedded systems, Arduino installations, and digital electronics. The LM340 was easy to use and relatively small, and with built-in protection, makes it simple to regulate voltage in anything DIY.
LM340 Voltage Output Formula:
Vout = 5V (Fixed for LM340-5.0)
Recommended Capacitor Values:
- Input Capacitor: 0.33µF
- Output Capacitor: 0.1µF
lm340 voltage regulator circuit
The LM340 family is a very common voltage regulator that still sells as it offers a stable 5 volts output, making it suitable to drive microcontrollers, sensors, and digital circuits. It has numerous current ratings (LM340-5.0, LM340T-5, etc.), and it features thermal shutdown and short-circuit protection. The device helps in making circuits easy to design because it negates the use of a complicated regulation system. The LM340 is perfect for beginners and professional electronic designs with a good supply of power, with very few external capacitors.
