Details
The LM723 is a monolithic integrated programmable voltage regulator, assembled in 14-lead dual in-line plastic package. The circuit provides internal current limiting. When the output current exceeds 150 mA an external NPN or PNP pass element may be used. Provisions are made for adjustable current limiting and remote shutdown.Features■ Input voltage up to 40 V■ Output voltage adjustable from 2 to 37 V■ Positive or negative supply operation■ Series, shunt, switching or floating operation■ Output current to 150 mA without external pass transistor■ Adjustable current limiting

FAQs
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.
