Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

SSP7903P30JR from Shanghai Siproin Microelectronics, in a TO-252. 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 Unregulated positive supply input. Absolute maximum 40 V (min -0.3 V); minimum operating input 2.2 V. Bypass to GND with a 10 µF (typ. 2.2 µF-4.7 µF) capacitor placed close to the pin.
2 GND power_in Ground reference for the regulator. In the TO-252 package this pin is electrically tied to the exposed heat-slug tab; use a single-point ground return to keep load-regulation error low. Quiescent current 1.6 µA typ.
3 VOUT power_out Regulated positive output. Fixed voltage set by ordering suffix ①② (3.0 V for the -30 variant); tolerance ±2%, dropout 20 mV @ 10 mA (1000 mV @ 1 A), max continuous output current 1 A, current-limit typ. 1.8 A, short-circuit current typ. 120 mA. Requires a 10 µF (typ. 2.2 µF-4.7 µF) output capacitor.

Provenance

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

  • Datasheet: Shanghai Siproin Microelectronics datasheet (11 pp, sha256 d1763cb71baebbea, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
