LP3201AB5F

LOWPOWER · DC-DC Converters · SOT-23-5

LP3201AB5F from LOWPOWER, 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 EN input Enable input, active high. Drive above VEN(H)=1.4V to enable the converter; drive below VEN(L)=0.4V to force shutdown (all functions disabled, supply current <1uA). Input low current 1uA @ VEN=5V.
2 GND power_in Device ground. Return for the input/output capacitors and the internal low-side synchronous rectifier.
3 LX power_out Switch-node output to the external inductor. Connects to the drains of the internal main P-channel (RDS(ON) ~270 mOhm) and synchronous N-channel (RDS(ON) ~130 mOhm) power MOSFETs. Absolute max -0.3V to 8.0V.
4 VIN power_in Power supply input, 2.5V to 5.5V (absolute max 8.0V, OVP at ~6.1V). Must be closely decoupled to GND with a 10uF or greater ceramic capacitor.
5 FB/VOUT input Feedback input. On the adjustable LP3201AB5F variant this is FB, tied to an external resistor divider from VOUT to set output voltage per VOUT = 0.6V * (1 + RUP/RDN), internal reference 0.6V. On the fixed-output variants (-12/-18/-33) this pin is tied directly to VOUT for internal feedback sensing. FB leakage 10nA typ.

CAD (KiCad official)

  • Symbol: LP3201AB5F
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: lp3201ab5f-etched.step / lp3201ab5f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lp3201ab5f.step / lp3201ab5f.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lp3201ab5f.step 85 KB You want the bare part, or you mark your own boards.
lp3201ab5f-etched.step 1.9 MB You want the part with LP3201AB5F already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 476 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.
