PJ54AM33SA

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

PJ54AM33SA from PJSEMI, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Regulated output of the LDO, available in fixed 1.8 V, 3.0 V, 3.3 V or 5.0 V versions, with VOUT to GND rated -0.3 V to +6 V.
2 GND power_in Ground reference; the input and output capacitors must be placed as close as possible to the VIN/VOUT and GND pins.
3 VIN power_in Power input with a 3 V to 45 V operating range (absolute maximum -0.3 V to +55 V), decoupled by a 1 µF ceramic capacitor placed close to the pin.

CAD (KiCad official)

  • Symbol: PJ54AM33SA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: pj54am33sa-etched.step / pj54am33sa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pj54am33sa.step / pj54am33sa.glb are the bare package body.
