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 | RESET | output | Active-low reset output, open-drain (TPS3828). Asserted low when VDD is below the 2.93 V threshold (VIT-), when MR is held low, or when the watchdog fails to be retriggered within tt(out). Requires an external pull-up resistor to a supply rail. IOL up to 1.2 mA at VOL <= 0.4 V. |+| 2 | GND | power_in | Ground reference for the device. All voltages are referenced to this pin. |+| 3 | MR | input | Manual reset input, active low. A low level on MR forces RESET active. Includes an internal 52 kOhm pull-up to VDD, so the pin may be left open if unused. VIL <= 0.3 x VDD; VIH >= 0.7 x VDD. |+| 4 | WDI | input | Watchdog input. A positive or negative transition on WDI within the watchdog timeout tt(out) (typ. 1.6 s) resets the watchdog timer. Failure to retrigger drives RESET active for td. Leaving WDI unconnected disables the watchdog. Minimum pulse width 100 ns. |+| 5 | VDD | power_in | Positive supply voltage input, monitored against the 2.93 V (typ) negative-going threshold VIT-. Operating range 1.1 V to 5.5 V (absolute max 6 V). Supply current IDD is typ. 15 uA (max 25 uA). A 0.1 uF ceramic bypass capacitor is recommended near the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `TPS3828-33DBVRDBVR`+- `TPS3828-33DBVRDBVRG4`+- `TPS3828-33DBVRDBVT`+- `TPS3828-33DBVRDBVTG4`++## CAD (KiCad official)++- Symbol: `TPS3828-33DBVR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps3828-33.pdf) (18 pp, sha256 `47c6c606c2571e78`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
