No external LDO needed if the rail is within this band. Housed in a 6-VDFN package measuring 7.00 mm x 5.00 mm x 0.90 mm, the land pattern matches standard 6-pin DFN footprints.","metaTitle":"DSC1221NE3-38M00000 38 MHz MEMS XO – AEC-Q100, CMOS","metaDescription":"Microchip DSC1221NE3-38M00000: 38 MHz XO (Standard), CMOS output, ±20 ppm stability, AEC-Q100 qualified, 6-VDFN package.
