S-1167B18-M5T1U

ABLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

S-1167B18-M5T1U from ABLIC, in a SOT-23-5. 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 VIN power_in Input voltage pin. Operating range 2.0 V to 6.5 V (absolute max VSS − 0.3 V to VSS + 7 V). Bypass with a 1.0 µF or greater ceramic capacitor (CIN) to VSS placed as close as possible to this pin.
2 VSS power_in Ground (GND) reference pin. Common return for input and output capacitors; wiring impedance to this pin should be minimized.
3 ON/OFF input Regulator enable pin. B-type (positive logic): 'H' (VSH ≥ 1.5 V) = ON, 'L' (VSL ≤ 0.3 V) = OFF. Input current
4 NC unconnected No connection. Pin is electrically open inside the package; may be left floating or tied to VIN or VSS per the datasheet note.
5 VOUT power_out Regulated output voltage pin. Fixed 1.8 V ±1.0% for S-1167B18; output current up to 150 mA (VIN ≥ VOUT(S) + 1.0 V). Requires a ≥1.0 µF output capacitor (CL) to VSS with ESR ≤ 1.0 Ω for phase compensation/stability. Do not allow VOUT to exceed VIN + 0.3 V (parasitic diode).

Provenance

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

  • Datasheet: ABLIC datasheet (None pp, sha256 0df82fa1e45e0b24, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
