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 | VOUT | power_out | Regulated 3.3V power output (±1% accuracy, up to 80mA). Requires a 1µF to 22µF output capacitor placed close to VOUT and GND for stability and improved PSRR/transient response. |+| 2 | SNS | input | Output voltage sense input; tie to VOUT for fixed 3.3V operation, or connect to a resistor divider from VOUT to GND for adjustable output. Abs-max on the -33 option is -0.3V to 6V; typical SNS input current ~0.85µA. |+| 3 | NC | unconnected | No internal connection; leave floating. |+| 4 | GND | power_in | Device ground reference. Should be tied to the exposed pad and to the ground planes with short, wide traces near input/output capacitors for best performance. |+| 5 | EN | input | Active-high enable input. VIH ≥ 3.0V enables regulation; VIL ≤ 0.6V drives shutdown mode (ISD ≈ 100nA typical, 500nA max). EN input current ~10nA (VEN = 36V). |+| 6 | NC | unconnected | No internal connection; leave floating. |+| 7 | NC | unconnected | No internal connection; leave floating. |+| 8 | VIN | power_in | High-voltage supply input, 3.0V to 110V recommended (abs-max 125V to GND). Requires a 1µF or larger input capacitor placed close to VIN and GND. |+| 9 | EP | passive | Exposed thermal pad on the ESOP-8 package. May be left floating or connected to GND; connecting to a copper ground pour is recommended to reduce θJA (55°C/W) and improve power dissipation (PD_max ≈ 1.82W at TA=25°C). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | DSTECH |+| Package | ESOP-8 |+| Category | PMIC |+| Pins | 9 |++## Ordering variants++- `DS8201-33F8`+- `DS8201-33F8B8`+- `DS8201-33F8S5`+- `DS8201-33F8A3`++## CAD (KiCad official)++- Symbol: `DS8201-33F8`+- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.41x3.3mm`+- 3D model: ESOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [DSTECH datasheet](docs/ds8201-33f8-datasheet.pdf) (None pp, sha256 `53613125cec676a8`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
