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 | EN | input | Enable control input. Force this pin above 1.5V to enable the chip; below 0.4V shuts down the device (Ish < 1uA). VEN abs max: -0.3V to VIN+0.3V. |+| 2 | GND | power_in | Ground pin. Device return for internal power MOSFETs and control logic. |+| 3 | LX | power_out | Switching node. Drains of the internal main (PFET, ~110 mOhm) and synchronous (NFET, ~80 mOhm) power MOSFETs. Connect to the external inductor. VLX abs max: -0.3V to VIN+0.3V. |+| 4 | VIN | power_in | Bias supply. Chip main power supply pin. Input voltage range 2.7V to 5.5V (abs max -0.3V to 6V). Bypass with a 22uF ceramic capacitor to GND. |+| 5 | FB | input | Feedback voltage to internal error amplifier. Regulated to 0.6V threshold (typ; 0.588V to 0.612V). Connect to output via a resistor divider to set VOUT = 0.6V * (1 + R1/R2). FB leakage < 0.2uA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | TSOT-25 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `AP3429KTTR-G1KTTR-G1`+- `AP3429KTTR-G1AKTTR-G1`++## CAD (KiCad official)++- Symbol: `AP3429KTTR-G1`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: TSOT-25 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP3429KTTR-G1.pdf) (11 pp, sha256 `81148b4230491ef2`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
