LP2985-33DBVR

LP2985-33DBVR is the tape-and-reel SOT-23-5 ordering code for the Texas Instruments LP2985-33 low-dropout regulator, listed as ACTIVE in the datasheet package option addendum (SLVS522 Rev O) with device markings LPFG / LPFL. This is the standard-grade 3.3 V code, and its output tolerance is 1.5 % - the tighter-tolerance A-grade sibling is a different ordering code whose figures are not used anywhere on this page. Read on its own rows it shows a dropout of 280 mV typical at the full 150 mA load (7 mV typical at 1 mA), a maximum input voltage of 16 V, a quiescent current of 850 µA typical at full load, a shutdown current of 0.01 µA typical and output noise of 30 µVRMS typical with a 10 nF bypass capacitor. The selection point is a micropower 3.3 V rail with a real shutdown pin: sensor and metering front ends that sleep for years can drop to near-zero draw without a load switch. Selection advice: TI also promotes a new-chip generation of this family on its product page; the figures here are the standard-grade rows of the current datasheet revision, so match the offered lot to the documented generation and grade before approving a substitute. Parameters verified against the TI LP2985 datasheet SLVS522 Rev O (package option addendum and electrical characteristics).
