About the Texas Instruments LM337 Series

ICBOMS is a China IC distributor and semiconductor supplier — an independent, Shenzhen-based overseas procurement agent for Texas Instruments LM337 Series components — sourcing Texas Instruments LM337 Series parts new and original only, across the authorized and vetted independent channel, with every lot authenticity-screened before shipment. The Texas Instruments LM337 Series series groups 3 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. Every variant in the range shares a common frequency - switching of 2MHz, function of Step-Down and I/O channels of 2. Variants differ by case, package and voltage - output (Min (Fixed)), so you can match the exact case your application requires using the selection guide below. The range mixes active and legacy part numbers, so you can source both current Texas Instruments LM337 Series variants and discontinued ones from a single page.
