TPS3840DL30DBVR 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 | tri_state | Open-drain active-low reset output asserted when MR is pulled to logic low or VDD drops below VIT-, released after reset delay time tD when MR floating and VDD above VIT+. |
| 2 | VDD | power_in | Input power supply voltage in range 1.5V to 10V monitored by internal comparator for voltage supervision. |
| 3 | GND | power_in | Ground reference. |
| 4 | MR | input | Active-low manual reset input; pull below 600mV to assert reset; output releases after delay tD when MR above 0.7*VDD. |
| 5 | CT | passive | Capacitor timing input for programmable reset delay; connect external capacitor (0 to 10µF) to set delay from 50µs to 6.2s, or leave floating for 50µs default. |
