'''LM338''' es un [[regulador de voltaje]] positivo ajustable diseñado para proporcionar una corriente de salida de hasta 5A.&lt;br /&gt;
&lt;br /&gt;
==Descripción==&lt;br /&gt;
&lt;br /&gt;
[[LM338]] es un [[regulador de voltaje]] positivo ajustable, capaz de suministrar 5A en un rango de salida de 1.2 a 32V. Es muy fácil de utilizar solo requiere dos [[resistencias]] externas para configurar el voltaje de salida, además tiene la característica especial que permite picos de [[corrientes]] de hasta 12A, por un corto periodo de tiempo, igualmente tiene incluido [[protección térmica]] contra sobrecargas. Su [[encapsulado]] es [[metálico]] de tipo [[TO-3]].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Principales características ==&lt;br /&gt;
&lt;br /&gt;
Voltaje de entrada: 4.2 a 40V&lt;br /&gt;
&lt;br /&gt;
Caída de voltaje típica: 1,5V&lt;br /&gt;
&lt;br /&gt;
Rechazo de ondulación típica: 80dB &lt;br /&gt;
&lt;br /&gt;
Potencia de disipación: limitada internamente&lt;br /&gt;
&lt;br /&gt;
Temperatura de soldadura en 10 segundos: 300ºC&lt;br /&gt;
&lt;br /&gt;
Temperatura de operación: 0 a 125ºC&lt;br /&gt;
&lt;br /&gt;
==Aplicaciones==&lt;br /&gt;
&lt;br /&gt;
Dentro de sus variadas aplicaciones tenemos: electrónica industrial y  del hogar como cargador de baterías, [[amplificadores de audio]], sistemas de iluminación [[Led,]] equipamientos de prueba y medición y reguladores lineales de alta potencia.&lt;br /&gt;
