This document provides technical specifications and application information for the LT123A/LT323A (and their LM123/LM323 counterparts), a precision 5-volt, 3-ampere voltage regulator. The devices offer an improved initial output voltage tolerance of 1% compared to previous versions.
| Output Voltage Tolerance (Initial) | 1% |
|---|---|
| Output Current | 3 Amp |
| Power Dissipation | 30 Watt |
| Operating Junction Temperature Range (LT323A/LM323) | 0°C to 125°C |
| Short Circuit Current Limit (Vin = 7.5V) | 4 A |
The device guarantees a 1% initial tolerance of the output voltage.
No, it does not strictly require one, but a solid tantalum capacitor is recommended to improve high-frequency impedance.
The typical quiescent current is 12 mA under specified conditions.
