Diving into the Pin Configuration and Features

Alright, let's get into the nitty-gritty. Understanding the LM723 pin configuration is essential for any project. Knowing what each pin does is the first step toward getting your circuit up and running. The LM723 typically comes in a 14-pin dual in-line package (DIP). While the pinout might seem a bit daunting at first, fear not! It's actually quite straightforward once you break it down.

Here's a quick rundown of the essential pins:

  • Pin 1 & 2 (Inverting and Non-inverting Input): These are the inputs to the internal operational amplifier (op-amp), used for error amplification and feedback. You'll typically connect a feedback network to these pins to control the output voltage.
  • Pin 3 (Non-inverting Input): Positive input terminal of the op-amp.
  • Pin 4 (V-): Negative supply voltage input. Connect this to the negative side of your power supply.
  • Pin 5 (Compensation): Used for frequency compensation to stabilize the op-amp. You'll usually connect a capacitor here.
  • Pin 6 (Vref): This provides an internal, temperature-compensated reference voltage, often around 7.15V. You can use this as a stable voltage source for your circuit.
  • Pin 7 (Output): The output of the internal op-amp.
  • Pin 8 (Current Limit): Allows you to set a current limit for your power supply, protecting it from overcurrent conditions.
  • Pin 9 (Current Sense): Connects to a resistor to monitor the output current.
  • Pin 10 (Output): The output of the pass transistor, where the regulated voltage appears.
  • Pin 11 (Boost): Used to connect the pass transistor. Helps to drive the output current.
  • Pin 12 (Shutdown): Allows you to shut down the regulator. When this pin is high, the regulator is disabled.
  • Pin 13 (V+): Positive supply voltage input. Connect this to the positive side of your power supply.
  • Pin 14 (Ground): The ground connection for the circuit.
