Absolute maximum -0.3 V to +15.0 V; monitored rail for reset detection. Detecting voltage VS = 4.2 V typ (4.05 V min, 4.35 V max) for the KIA7042. |+| 2 | GND | power_in | Ground / VEE reference. All voltages referred to this pin. |+| 3 | OUT | output | Open-collector active-low reset / detector output. Pulls low when VCC drops below the detecting voltage; requires an external pull-up resistor (RL, e.g. 200 ohm test, 1 kohm typical application). VOL <= 0.4 V at RL=200 ohm; leakage IOH <= 0.1 uA at VCC=15 V; guaranteed to sink >=20 mA at 25 C (>=16 mA over -30 to +75 C); minimum operating VCC for valid low = 0.8 V typ. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | KEC Semicon |+| Package | TO-92-2.54mm |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `KIA7042AP-ATAP`+- `KIA7042AP-ATAF`+- `KIA7042AP-ATAT`++## CAD (KiCad official)++- Symbol: `KIA7042AP-AT`+- Footprint: `Package_TO_SOT_THT:TO-92_Inline`+- 3D model: TO-92-2.54mm (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [KEC Semicon datasheet](docs/kia7042ap-at-datasheet.pdf) (4 pp, sha256 `ee964c11be24fd17`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
