TPS3840PL27DBVR 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 (TPS3840PL) that is driven low when VDD falls below VIT- or MR is pulled low, and returns high after the reset delay tD once VDD rises above VIT+ and MR is released; VOL is at most 200 mV at 2 mA sink and VOH is at least 0.8×VDD at 2 mA or 5 mA source. |
| 2 | VDD | power_in | Input supply voltage that is monitored against the fixed threshold VIT-; the recommended operating range is 1.5 V to 10 V and the absolute maximum rating is 12 V. |
| 3 | GND | power_in | Ground reference pin; a 0.1 µF to 1 µF bypass capacitor is recommended between VDD and GND for noisy applications. |
| 4 | MR/NC | input | Active-low manual reset input that asserts RESET when pulled below VMR_L (max 600 mV); it may be left floating (internal 100 kΩ pull-up to VDD), and VMR must not exceed VDD. |
| 5 | CT | passive | Reset delay programming pin where a capacitor to GND (not greater than 10 µF) sets tD, and leaving it floating gives the minimum fixed delay of 50 µs. |
