## Description

The LM340AT from Texas Instruments is a monolithic 3-terminal positive voltage regulator designed for a wide range of applications. It provides a fixed 5V output voltage with an output current capability of up to 1.5A. This regulator family includes internal current-limiting, thermal shutdown, and safe-area compensation, making them highly reliable.

The LM340AT features a wide input voltage range and is suitable for local on-card regulation to eliminate noise and distribution problems. It operates within a temperature range of 0°C to 125°C and is housed in a TO-220 package.

Key electrical characteristics include line regulation of 0.01%/V and load regulation of 0.3%/A for the LM340A variant. Output voltage tolerance is typically ±2% at 25°C for the LM340A. The device does not require output capacitance for stability, although input bypassing may be needed if the regulator is located far from the power supply filter capacitor.
