PDF reference listing Ricoh component marking codes, the short codes printed on small SMD packages. Although filed as a schematic, it is really a lookup document for working out the real part number from a cryptic top mark. Ricoh makes LDO regulators, DC-DC converters and voltage detectors that are common on laptop and phone boards. A technician uses it to identify a burnt or unlabelled chip and order a replacement, and should cross-check the package type and pinout against the datasheet.
