LR6302A33P

LRC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

LR6302A33P from LRC, in a SOT-89-3. 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 VSS power_in Ground / negative supply return for the LDO. Connect to system ground close to the CIN and COUT capacitor grounds to minimize impedance in the reference return path.
2 VIN power_in Unregulated supply input, 2.5V to 18V (absolute max 24V). Bypass with a 1µF ceramic CIN close to the pin; if driven from a live source through a high-Q MLCC, consider a small (~3Ω) series resistor to damp start-up voltage transients per the application notes.
3 VOUT power_out Regulated 3.3V output (LR6302A33 option), up to 300mA continuous with 160mV typical dropout at 100mA. Requires a 1µF output capacitor from VOUT to VSS placed close to the pin for loop stability; ceramic acceptable for improved transient response.

Provenance

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

  • Datasheet: LRC datasheet (15 pp, sha256 aef2362d67da51ad, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
