TPS3840PL30DBVR 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 push-pull reset output that is driven low when VDD falls below VIT- or MR is pulled low, and stays low for the reset delay tD after release before returning high. |
| 2 | VDD | power_in | Input supply voltage that is monitored against the threshold VIT-; the recommended operating range is 1.5 V to 10 V and the absolute maximum is 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); it may be left floating (internal 100 kΩ pull-up to VDD) and must never be driven above VDD. |
| 5 | CT | passive | Reset delay programming pin where a capacitor from CT to GND sets tD (10 µF maximum recommended), and leaving it floating gives the minimum fixed delay of 50 µs. |
