PJ9193M30SE

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

PJ9193M30SE from PJSEMI, 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 Power input voltage. Operating range 2V to 6.5V (absolute max -0.3 to 7V). Decouple to GND with a 1µF ceramic capacitor placed as close as possible to the pin.
2 GND power_in Device ground reference. Common return for VIN, VOUT and EN. Route with a wide copper trace for good thermal and noise performance.
3 EN input Chip enable input, active high (CMOS logic). VIH ≥ 1.2V enables the regulator; VIL ≤ 0.4V puts it in shutdown (<1µA). High-impedance pin - cannot be left floating; tie to VIN to keep the part permanently on. Absolute max ±0.3V relative to VIN.
4 NC unconnected No internal connection. Leave floating or tie to GND per PCB convention.
5 VOUT power_out Regulated output voltage - 3.0V fixed for the -30 option, up to 300mA (typical current limit 450mA, short-circuit current 50mA). Requires a minimum 1µF ceramic output capacitor (X7R/X5R) placed close to the pin for stability.

Two STEP files. Same geometry, different body top:

File Size Use it when
pj9193m30se.step 85 KB You want the bare part, or you mark your own boards.
pj9193m30se-etched.step 2.4 MB You want the part with PJ9193M30SE already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 575 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: PJSEMI datasheet (11 pp, sha256 9a82ee51ef372c12, 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).
