LP3993-16B3F

LOWPOWER · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

LP3993-16B3F from LOWPOWER, in a SOT-23-3. 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 Device ground reference. Return path for load current, quiescent current, and the internal 1.2V bandgap reference. Return the input/output capacitor grounds to a clean analog ground plane at this pin.
2 OUT power_out Regulated output pin. Supplies up to 200mA (250mA current limit typ.) at the factory-trimmed output voltage. Requires a ≥10µF ceramic output capacitor (ESR >25mΩ) located within 0.5 inch of this pin for stability.
3 IN power_in Supply input pin. Accepts VOUT+1V up to 28V (32V abs-max). Requires a ≥10µF ceramic or tantalum bypass capacitor located within 0.5 inch of this pin.

Provenance

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

  • Datasheet: LOWPOWER datasheet (None pp, sha256 a861a153d12d4752, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
