TLV1117LV33DCYR

TLV1117LV33DCYR is the tape-and-reel SOT-223 ordering code for the Texas Instruments TLV1117LV fixed 3.3 V low-dropout regulator, listed as ACTIVE; the stock flag on the store page is inventory, not lifecycle. Read on the datasheet (SBVS160): dropout of 455 mV at 1 A for the 3.3 V output, typical accuracy of 1.5 %, PSRR of 65 dB at 1 kHz and a minimum specified current limit of 1.1 A. The LV generation is a different device from the standard TLV1117, and the differences are the selection point: an input of 2 V to 5.5 V (6 V absolute maximum) against the standard part’s 15 V-class input, 1 A of output against 800 mA, quiescent current of 100 µA maximum — roughly 500 times lower than the standard 1117 family — fixed outputs only, and stability with no minimum load current and with 0-Ω ESR ceramic capacitors. Selection advice: choose the LV code for low-voltage rails where standby current is budgeted; a design feeding the regulator from 9 V or 12 V belongs to the standard TLV1117 family, because the LV part’s recommended input range ends at 5.5 V and its 6 V figure is an absolute-maximum stress rating, not a working target. DCYR denotes the SOT-223 (DCY) package on a 2,500-piece reel. Parameters verified against the TI TLV1117LV datasheet SBVS160 (features and electrical characteristics) and the TI product page.
