ToshibaLM 338K TOSHIBA

The Toshiba LM338K Adjustable Positive Linear Voltage Regulator 1.2-32V 5A TO-3 is an LM338K-family high-current adjustable positive linear regulator providing 1.2-32V output and up to 5A continuous current with proper heatsinking.

Technical description

The K version uses a metal TO-3 package. The LM338 family supports adjustable output from 1.2V to 32V, 5A rated current and current limiting, thermal limiting and short-circuit protection. Maximum input-to-output differential is 40V.

Indicative applications

Suitable for high-current adjustable power supplies, chargers, current regulators and bench supplies.

Compatibility note

Operation at 5A requires substantial heatsinking and careful power-dissipation calculation. The TO-3 metal case is electrically connected to the regulator and must be insulated where required.
