LDOROHM LDO Finder

ROHM's LDO Finder enables selection of the ideal IC from among a broad lineup. Simply inputting the usage conditions makes it possible to not only narrow down IC selection based on application requirements, but compare up to 6 models according to overcurrent protection characteristics and input/output voltage difference. In addition, users can sort by mounting area and junction temperature, shortening selection time considerably.
