LM323 Datasheet – 3 Amp, 5 Volt Positive Regulator – TI

Part Number : LM323

Function : 3-Amp, 5-Volt Positive Regulator

Package : Metal Can TO-3 Type

Manufacturers : Texas Instruments

Pinouts :

LM323 datasheet


Description :

The LM123 is a three-terminal positive regulator with a preset 5V output and a load driving capability of 3 amps. New circuit design and processing techniques are used to provide the high output current without sacrificing the regulation characteristics of lower current devices.

The LM323A offers improved precision over the standard LM323-N. Parameters with tightened specifications include output voltage tolerance, line regulation, and load regulation.


1. Ensured 1% Initial Accuracy (A Version)
2. 3 Amp Output Current
3. Internal Current and Thermal Limiting
4. 0.01Ω Typical Output Impedance
5. 7.5V Minimum Input Voltage
6. 30W Power Dissipation
