LM323 Pin Configuration
Firstly, as a linear voltage regulator, the LM323 is a 3-terminal positive voltage regulator that comes with a preset 5V output. It also comes with a load-driving capability of 3 A. Here, new circuit design and processing techniques are used to provide high output current without sacrificing the regulation of lower current devices.
Also, in electronics, you may come across a pinout. It is a cross-reference between the pins, or contacts, of an electronic component or an electrical connector and their functions. At this point, we will look at how to configure an LM323 pin.
| Pin Number | Pin Name | Description |
| 1 | The input voltage pin | The pin under which input current passes through the system |
| 2 | Ground pin. | This pin is connected to the ground of the device |
| 3 | Output voltage pin. | This pin is under which the current-voltage leaves the device. |
Characteristics of LM323
The LM323 regulator has several characteristics worth noting.
- Output Voltage: 5V (Fixed)
- Positive Voltage Regulator
- Input Voltage: 7.2V to 20V
- Output Current: 3A
- Voltage Tolerance: 2%
- Maximum Output Current: 15A (With Series Pass transistor)
- The operating junction temperature is 125°C (maximum)
- Found in To-220 and metal can package
LM323 Equivalents
The most notable alternatives are LM317 and LM7805. They include the following:
The LM317 device is a 3-terminal adjustable positive-voltage regulator. It can supply more than 1.5 A over an output-voltage range of 1.25 V to 37 V.
The LM7805, on the other hand, finds heavy usage in almost all electronic projects because it offers a constant +5V output voltage for a variable input voltage supply.

How to Use LM323
All you need to do is connect to the input filter capacitor. The value needs to be 0.33uF or higher than an output filter capacitor of 0.1uF or more, depending on the output current.
Consequently, you’ll get +5V regulators on the output pin, and you need to remember that the minimum input voltage needs to be 7.5V minimum.
Besides the fixed voltage regulator, the LM323 can act as a constant load current provider source when one uses it as a resistor. It can also act as a variable voltage regulator when one uses it with an Op-Amp, making it highly suitable in plenty of applications.
