| This is from service manual for COK001. These are all voltage regulators labeled with same "M" <br>

| The voltage regulator schematics in the COK-001 manuals seems different pinout of what i meassured in 348A and 463A and different features, 348A and 463A has two separated output voltages each, and are driven by syscon

| Btw... the photos of 348A and 463A was labeled "voltage regulator" as a simplification because probably the real name of the component is more technicall
