TLV840MADL31DBVRQ1 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 output reset signal driven low when VDD falls below 3.1-V threshold and held low for programmable delay time after VDD recovery; open-drain topology requires external pull-up resistor to VDD or higher voltage. |
| 2 | VDD | power_in | Input supply voltage monitored by internal comparator; operating range 0.7 V to 6 V. |
| 3 | GND | power_in | Ground reference. |
| 4 | MR | input | Manual reset input; pulling below 0.3×VDD for ≥500 ns asserts reset output; internally pulled up with 100 kΩ to VDD. |
| 5 | CT | passive | Capacitor time delay pin; connect up to 10 µF capacitor to GND for programmable reset delay from 40 µs (floating pin) to approximately 6.2 seconds. |
