REGULADORES SMD
Durante las reparaciones que realizamos nos encontramos con reguladores de voltaje cuyo número de identificación no lo encontramos en los manuales SMD estándar como es el caso de los reguladores con encapsulado SOT-223, SOT-23 (3, 5 y 6 pines) Y MSOP (Mini Small Outline Plastic Package).
Estos utilizan un código de 4 dígitos dado su reducido tamaño (Ver tabla).

Cuando el regulador de voltaje viene en encapsulado DPAK y D2PAK trae su número de identificación completo.
Cuando el regulador viene en encapsulado SOIC trae su número de identificación completo como es el caso de los reguladores de la serie 78XX y 79XX.
Otro tipo de encapsulado en que pueden presentarse los reguladores:
Aplicación típica de un regulador LP2980-5 (SOT-23) y un regulador
LM2940 (SOT-223).
