MM1899 Description
MITSUMI Low noise 300mA LDO MM1899 Series Low noise 300mA LDO Monolithic IC MM1899 Series 1. It is remended to layout the VIA for heat radiation in the GND pattern of reverse (of IC) when there is the GND pattern in the inner layer (in using multiplayer substrate). By increasing these copper foil pattern area of PCB, Power dissipation improves.
