IDCHIP · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

1117-5 from IDCHIP, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the fixed-output version. On the adjustable (-ADJ) variant this same pin becomes ADJ (feedback input tied to the external resistor divider). For the -5.0 (fixed 5.0V) part, tie directly to system ground.
2 VOUT power_out Regulated 5.0V output. Requires a minimum 22µF tantalum output capacitor for stability. Guaranteed output range 4.900V-5.10V over 0-1A load and 6.5V ≤ VIN ≤ 12V.
3 VIN power_in Unregulated input supply. For the 5.0V fixed output, VIN must be at least 6.5V (dropout 1.2V at 1A) up to an absolute maximum of 12V. A 10µF bypass capacitor is recommended.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: IDCHIP datasheet (9 pp, sha256 ee7ebf60d4d36188, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
