LM338T Description

Short technical summary and product information.

The LM338T from Texas Instruments is a versatile adjustable positive linear voltage regulator designed for applications requiring high output current. It can supply in excess of 5A over an output voltage range adjustable down to 1.2V, with a maximum input voltage of 40V.

 

Key electrical specifications include a typical quiescent current of 0.045mA, a PSRR of 10dB at 100 KHz, and an accuracy of 2.4%. The device offers protection features such as over-temperature and short-circuit protection, with current limiting that remains constant with temperature. It operates within a temperature range of 0°C to 125°C.

 

Packaged in a standard TO-220-3 through-hole configuration, the LM338T is suitable for various power supply designs. Its ease of use, requiring only two resistors to set the output voltage, combined with outstanding load and line regulation, makes it a comparable alternative to many commercial power supplies. The regulator also features time-dependent current limiting, allowing for peak currents up to 12A for short durations, beneficial for heavy transient loads and fast start-up.
