TPS3840DL42DBVR 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 | Active-low open-drain reset output that is pulled low when VDD falls below VIT- or MR is pulled low, requires an external pull-up, and has a recommended voltage range of 0 V to 10 V with a current limit of ±5 mA. |
| 2 | VDD | power_in | Supply input and monitored voltage with a recommended range of 1.5 V to 10 V and an absolute maximum of 12 V. |
| 3 | GND | power_in | Ground reference pin. |
| 4 | MR/NC | input | Active-low manual reset input that asserts RESET when pulled below VMR_L (600 mV max) and must not exceed VDD; it has an internal 100 kΩ pull-up and can be left floating when unused. |
| 5 | CT | passive | Reset delay timing pin where a capacitor of up to 10 µF connected to GND sets tD, and leaving it floating gives the minimum fixed delay of 50 µs. |
