Drive above 1.5V (typ 1.15V rising threshold, 140mV hysteresis) to turn the regulator on; drive below 0.3V to shut it down. Must not be left floating. |+| 2 | GND | power_in | Ground return for the device. Should be tied to a large copper pour for thermal dissipation. |+| 3 | SW | power_out | Switch node output. Connected to the drains of the internal P-ch and N-ch power MOSFETs and drives the external inductor. Rated for 3A peak sink/source current. |+| 4 | IN | power_in | Power supply input, 2.5V to 5.5V operating range (6.0V absolute max). Must be closely decoupled to GND with a 10µF or greater ceramic capacitor. |+| 5 | FB | input | Output voltage feedback input. Connect to the midpoint of an external resistor divider from VOUT to GND; regulates to the internal 0.600V reference (VOUT = 0.6V × (R1+R2)/R2). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | RYCHIP Semiconductor Inc |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `RY3420ADYLL`++## CAD (KiCad official)++- Symbol: `RY3420`+- 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:** [RYCHIP Semiconductor Inc datasheet](https://datasheet.lcsc.com/datasheet/pdf/65270aac3100a121236d8fe2969a76d0.pdf) (9 pp, sha256 `e2817c95aff7799d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
