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 | Supply input voltage. Recommended operating range 2.5V to 13.2V (absolute max 15V). For normal regulation VIN must be at least VOUT + 0.165V (dropout). A 1.0μF input capacitor (CIN) is recommended. |+| 2 | GND | power_in | Device ground and current return. Ground pin current is typically 95μA at IOUT=0μA and up to ~1.3mA at IOUT=150mA. |+| 3 | EN | input | Enable input, CMOS/TTL compatible. Logic high (VEN ≥ 2.0V) enables the regulator; logic low (VEN ≤ 0.4V) puts the device into low-power shutdown (ISTD ~0.01μA typ, 1μA max). Do not float; tie to VIN if always-on operation is desired. Absolute max VEN = 15V. |+| 4 | BYP | passive | Bypass pin for low-noise operation on the fixed-voltage (AP2202K-3.3) version. Connect an external capacitor (typ. 100pF) from BYP to GND to bypass the internal bandgap reference, reducing output noise (typ. 260 nV/√Hz with CBYP=100pF, COUT=2.2μF, IOUT=50mA). On the AP2202-ADJ variant this pin is instead ADJ (feedback input). |+| 5 | VOUT | power_out | Regulated output voltage, 3.3V ±1% (fixed for the -3.3 option). Delivers up to 150mA. Requires a 2.2μF output capacitor (COUT) for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated AP2202K 3 3TRG1 |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `AP2202K-3.3TRG1K-3.3TRG1`+- `AP2202K-3.3TRG1K-2.5TRG1`+- `AP2202K-3.3TRG1K-2.6TRG1`+- `AP2202K-3.3TRG1K-2.8TRG1`+- `AP2202K-3.3TRG1K-3.0TRG1`+- `AP2202K-3.3TRG1K-ADJTRG1`+- `AP2202K-3.3TRG1Y-3.3TRG1`+- `AP2202K-3.3TRG1Y-2.5TRG1`+- `AP2202K-3.3TRG1Y-2.6TRG1`+- `AP2202K-3.3TRG1Y-2.8TRG1`+- `AP2202K-3.3TRG1Y-3.0TRG1`++## CAD (KiCad official)++- Symbol: `AP2202K-3.3TRG1`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated AP2202K 3 3TRG1 datasheet](https://www.diodes.com/assets/Datasheets/AP2202K-3.3TRG1.pdf) (26 pp, sha256 `ac902c499d16dc61`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
