TPS3825-33QDBVRQ1 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RESET | output | Low-level active reset output with push-pull output stage, asserted low when VDD falls below VIT- (2.88-2.93-3.0 V) or MR pulled low, released high 200 ms after VDD exceeds VIT- + 30 mV. |
| 2 | GND | power_in | Ground connection providing negative supply reference. |
| 3 | RESET | output | High-level active reset output with push-pull output stage, asserted high when VDD falls below VIT- (2.88-2.93-3.0 V) or MR pulled low, released low 200 ms after VDD exceeds VIT- + 30 mV. |
| 4 | MR | input | Manual reset input with internal pull-up resistance (~90 kΩ), pulling to VIL (≤0.3 × VDD) forces RESET active for timeout period after returning to VIH, may be left unconnected or tied to VDD when not used. |
| 5 | VDD | power_in | Positive supply voltage input (1.1-5.5 V) monitored internally against VIT- (2.88-2.93-3.0 V) for -33 variant, with 0.1 μF ceramic bypass capacitor recommended nearby for optimum threshold stability. |
