"description": "Advanced Monolithic Systems AMS1117 - the original three-terminal 1 A low-dropout linear voltage regulator. Fixed 1.5, 1.8, 2.5, 2.85, 3.3 and 5.0 V versions or adjustable around a 1.25 V reference. Operates down to 1 V input-to-output differential (1.3 V max dropout at 0.8 A), trimmed on-chip to 1.5 %, with internal current limiting (0.9-1.5 A) and thermal shutdown at 165 C. 15 V absolute maximum input. Offered in SOT-223, TO-252 (DPAK) and 8-lead SOIC; on SOT-223 and TO-252 the metal tab is VOUT. The 2.85 V version is the SCSI-2 active-termination voltage and is not carried by the UMW second source.",
