LM338T Description

Short technical summary and product information.

The LM338T is a versatile adjustable voltage regulator manufactured by Texas Instruments. Designed for use in a TO-220 package, it is suitable for through-hole mounting.

This regulator can deliver an output current of up to 5A, making it suitable for higher power applications. It accepts an input voltage ranging from a minimum of 4.2V to a maximum of 40V. The output voltage is adjustable, with a minimum specified voltage of 3V. A key characteristic is its low dropout voltage, specified at a typical 3mV, which minimizes power loss.

The LM338T operates within a temperature range of 0°C to 125°C. Its maximum power dissipation is rated at 25W. The quiescent current is typically 3mA, and it features a Power Supply Rejection Ratio (PSRR) of 75dB, indicating good noise filtering capabilities.

This component is well-suited for various power supply designs, battery chargers, and regulated power systems where adjustable output voltage and significant current handling are required.
