TPS3838K33DBVT 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 | CT | passive | Capacitor time delay pin: connect to GND to set the reset delay to 10 ms, or connect to VDD to set it to 200 ms. |
| 2 | GND | power_in | Ground reference; all voltage values in the datasheet are specified with respect to GND. |
| 3 | MR | input | Manual reset input: a logic-low drives RESET active, and it should be connected to VDD to minimize current consumption when unused. |
| 4 | RESET | output | Active-low open-drain reset output (TPS3838) that asserts low when VDD falls below VIT or MR is low and releases high after the reset delay tD once VDD exceeds VIT plus VHYS and MR is high; an external pullup is required. |
| 5 | VDD | power_in | Input supply voltage monitored by the device; recommended supply range is 1.6 V to 6 V with an absolute maximum of 7 V. |
