常見問題解答

What is LM723N?

The LM723N is a voltage regulator integrated circuit (IC) designed by Texas Instruments. It is widely used for regulating and controlling the output voltage of power supplies and other electronic systems. The LM723N is versatile and can be configured to operate as a linear regulator, a current regulator, or a voltage reference.

How Does LM723N Work?

The LM723N operates by comparing the output voltage with a stable internal reference and adjusting the control element to maintain a constant output. It uses external components to set the desired output voltage and current limit. The device can be used in a wide range of applications, including adjustable voltage regulators, precision current regulators, and voltage reference sources.

How Many Pins does LM723N have and What are the Functions of the Pinout Configuration?

The LM723N is housed in an 14-lead PDIP (Plastic Dual Inline Package) package. The pinout configuration includes:

  • V+: Positive power supply pin.
  • V-: Ground pin.
  • OUTPUT: Regulated output voltage pin.
  • ADJ: Adjustable pin for setting output voltage.
  • IN-, IN+: Inverting and non-inverting inputs for error amplifier.
  • REFERENCE: Voltage reference output pin.
  • COMP: Compensation pin for frequency response adjustment.
  • VB: Voltage boost pin for series pass transistor.
  • VZ: Zener diode connection pin for current and voltage limiting.

What are the Pros and Cons of LM723N?

Pros:

  • Versatility: Can be used as a voltage regulator, current regulator, or voltage reference.
  • Flexible Configuration: External components enable precise adjustment of output voltage and current limit.
  • Wide Application Range: Suitable for various power supply and regulation applications.
  • Stable and Reliable: Provides stable output even with varying load conditions.
  • Industry Standard: Widely supported and documented in the electronics industry.

Cons:

  • External Components: Requires additional components for operation, which may increase system complexity.
  • Obsolete: The LM723N is considered an older device, and newer alternatives may offer additional features.
  • Package Size: The 14-lead PDIP package may not be suitable for space-constrained designs.

Are There Any Equivalents/Alternatives to LM723N for Recommendation?

  • The LM317 from Texas Instruments is a popular alternative for adjustable voltage regulation applications.
  • Other alternatives to the LM723N include the LT1083 and LT1963A from Linear Technology.
