TLV840CADL29DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RESET | output | Active-low, open-drain reset output. Asserted low when VDD falls below the negative voltage threshold (VIT-). RESET remains asserted for the delay time tD after VDD rises above VIT+ (= VIT- + VHYS). Requires an external pull-up resistor to VDD (or another rail up to 6 V); absolute-max current +/-20 mA, recommended <= 5 mA. |
| 2 | VDD | power_in | Input supply voltage; also the monitored rail. Operating range 0.7 V to 6 V (abs-max 6.5 V). Typical supply current 120 nA. Bypass with a local ceramic capacitor close to the pin. |
| 3 | GND | power_in | Device ground reference. |
| 4 | NC | unconnected | No connect. Pin may be left floating; TI recommends tying to GND. On the TLV840M variant this pin is the manual-reset MR input, but on the TLV840C ordered here it is NC. |
| 5 | CT | passive | Capacitor time-delay pin. Program the reset time delay tD by connecting an external capacitor between CT and GND. Leave floating for the minimum ~40 us delay. Abs-max voltage -0.3 V to VDD+0.3 V. |
