Description

LM723 Precision Adjustable Power Controller

Technical Specifications of LM723 Voltage Regulator IC

• Input Voltage: Supports a maximum positive supply input up to 40V DC.

• Output Voltage: Adjustable range spanning from 2V minimum to 37V maximum.

• Reference Voltage: Provides a stable internal reference of approximately 7.15V.

• Current Capacity: Integrated output current of 150mA without external pass transistors.

• Frequency Compensation: Dedicated pin for 100pF noise reduction capacitor integration.

• Temperature Range: Reliable operation within ambient temperatures of -55°C to 125°C.

• Package Type: Available in high-reliability 14-pin Dual In-line Package (DIP).

• Versatility: The LM723 Voltage Regulator IC supports linear and switching regulator modes.

Usage and Circuit Configuration

• First, connect the V+ pin to your unregulated DC input source.

• Next, use the non-inverting input to set the required reference voltage.

• Then, bridge a series pass transistor to increase output current to 10A.

• Afterward, utilize the current sense pins for foldback or limiting protection.

• Consequently, this setup ensures a highly stable output under varying load conditions.

• Finally, refer to the datasheet for specific resistor values for 2V-7V regulation.

Advantages and Disadvantages of LM723 Voltage Regulator IC

• Pros: Offers exceptionally low ripple and precise voltage regulation for lab power supplies.

• Furthermore, it allows for extremely flexible current limiting and temperature control applications.

• Cons: Requires multiple external components compared to fixed three-terminal regulators like LM7805.

• Additionally, the circuit design is more complex for beginner electronics hobbyists.

Precautions and Installation Safety

• Warning: Never exceed the 40V input limit to avoid internal silicon breakdown.

• Avoid operating without a frequency compensation capacitor to prevent high-frequency oscillations.

• Do not short-circuit the output if the current limiting circuit is not engaged.

What is Included in the Package

• 1x LM723 Voltage Regulator IC (DIP-14 through-hole mount).

• Antistatic protective packaging to prevent damage during shipping and handling.
