The LM338 is an adjustable 3-terminal positive voltage regulator capable of providing up to 5 amperes of output current. To increase the output current capability, you can connect multiple LM338 ICs in parallel. When you connect them in parallel, each IC will share the load current, allowing you to achieve higher total current handling capacity. […]
