@@ -0,0 +1,47 @@+# AMS1117-5.0++**Advanced Monolithic Systems** · 1 A LDO regulator (fixed 5 V) · SOT-223++The 5 V version of the AMS1117, a 1 A low-dropout linear regulator in the SOT-223 tab package. It regulates a higher unregulated input down to a fixed 5 V with 1.5% reference tolerance, dropping about 1.3 V at 0.8 A, so a 7-12 V input gives a clean 5 V rail for logic, USB, and sensors. Internal current limiting and thermal shutdown protect it, and a 10 uF output capacitor keeps it stable. The tab (pin 2) is the output and the thermal path. Use the AMS1117-3.3 for 3.3 V rails.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Ground reference for the fixed-output regulator. Internally the top of the divider is Kelvin-connected to VOUT so this pin can be used for negative-side sensing at the load. |+| 2 | VOUT | power_out | Regulated 5.0V output. Requires a 22uF solid tantalum output capacitor for frequency compensation and stability across all load conditions. Delivers up to 1A with 1.3V max dropout at 0.8A. |+| 3 | VIN | power_in | Unregulated input supply. Must be at least VOUT + 1.3V (dropout) up to a 15V absolute maximum. An input capacitor is recommended when the source impedance is significant or when the input line is long. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Fixed LDO linear regulator |+| Output voltage | 5.0 V (1.5% tol) |+| Output current | up to 1 A |+| Dropout | 1.3 V max at 0.8 A |+| Protection | Current limit + thermal shutdown |+| Output cap | 10 µF (stability) |+| Package | SOT-223 (tab = VOUT) |+| Line regulation | typ. 0.2% |++## Ordering variants++- `AMS1117-5.0 (SOT-223)`+- `AMS1117-5.0/TR (SOT-223, tape & reel)`++## CAD (KiCad official)++- Symbol: `Regulator_Linear:AMS1117-5.0`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223 (KiCad packages3D)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Advanced Monolithic Systems datasheet](http://www.advanced-monolithic.com/pdf/ds1117.pdf) (8 pp, sha256 `189a2651878a87d5`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
