LP2980IM5-ADJ

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

LP2980IM5-ADJ from Texas Instruments, 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 supply pin. Operating range 2.5 V to 16 V (survival -0.3 V to 16 V). A 1 uF input capacitor is recommended for stability.
2 GND power_in Common ground reference (device substrate). Ground pin current is typically 320 uA at 50 mA load and 80 uA at 1 mA load.
3 ON/OFF input Active-high enable input. VIH >= 1.4 V (typ) enables the regulator; VIL <= 0.55 V (typ) puts the device into shutdown (<1 uA quiescent). Must be actively terminated; tie to VIN if the shutdown function is not used.
4 ADJ input Output voltage feedback / adjust pin. Internal 1.23 V reference; connect a resistor divider from VOUT to ADJ to GND to set VOUT = 1.23 * (1 + R1/R2). ADJ pin bias current typically 150 nA.
5 VOUT power_out Regulated output voltage. Adjustable from 1.23 V to 15 V, 50 mA continuous (150 mA typical peak), short-circuit protected. Requires a minimum 2.2 uF output capacitor for stability.

Two STEP files. Same geometry, different body top:

File Size Use it when
lp2980im5-adj.step 85 KB You want the bare part, or you mark your own boards.
lp2980im5-adj-etched.step 2.3 MB You want the part with LP2980IM5-ADJ already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 561 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: Texas Instruments datasheet (17 pp, sha256 7e32119f85ce068f, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
