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 | I | power_in | Regulator input supply. Nominal operating range 5.5 V to 42 V (abs. max -0.3 V to 45 V). Must be blocked to ground directly at the IC with a ceramic capacitor. Typically connected permanently to VBAT. |+| 2 | GND | power_in | Device ground reference. Internally connected to the heat slug/tab; connect the tab to GND and to the PCB heatsink area for thermal dissipation (RthJC ~6 K/W). |+| 3 | Q | power_out | Regulated 5.0 V ±2% output, up to 300 mA (typ. dropout 250 mV @ 200 mA). Must be blocked to ground with a capacitor close to the IC terminals: CQ ≥ 470 nF, ESR ≤ 10 Ω at 10 kHz. Output-current limit min 301 mA; internal sink circuitry keeps VQ ≤ 5.5 V under reverse-current conditions. |+| TAB | GND | power_in | Heat slug / exposed tab of the PG-TO252-3 package. Internally connected to GND (pin 2); must be soldered to the GND heatsink copper area on the PCB for thermal performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Infineon Technologies |+| Package | TO-252 |+| Category | Power Management (PMIC) |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `TLE7274-2D`+- `TLE7274-2D2G`+- `TLE7274-2G`+- `TLE7274-2D2E`+- `TLE7274-2E`++## CAD (KiCad official)++- Symbol: `TLE7274-2D`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Infineon Technologies datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588912724965265408) (19 pp, sha256 `584877d82d9770ac`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
