TPS7A6301QPWPRQ1 from Texas Instruments, in a HTSSOP-14. 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 | VIN | power_in | Unregulated input voltage pin, with a recommended range of 7 V to 40 V and a 45 V absolute maximum for transients; a bypass capacitor between VIN and GND dampens line transients. |
| 2 | nRST | output | Open-drain reset output that requires an external pullup resistor to VOUT, with a 7 V absolute maximum and a recommended low-voltage range of 0 V to 5.25 V. |
| 3 | FB | input | Feedback input that senses the output voltage for the error amplifier, applicable only to the adjustable-output TPS7A6x01-Q1 devices, with a 7 V absolute maximum. |
| 4 | GND | power_in | Signal ground pin of the device, to which all voltages are referenced and to which the output capacitor COUT is connected. |
| 5 | EN | input | High-voltage-tolerant chip enable input with an internal pulldown and a recommended range of 4 V to 40 V, where a high level turns the regulator on, it should be tied to VIN for self-bias, and leaving it unconnected keeps the device disabled. |
| 6 | RDELAY | output | Reset delay timer pin that programs the reset delay with an external capacitor CDLY to ground, with a 7 V absolute maximum. |
| 7 | VOUT | power_out | Regulated output (3.3 V, 5 V, or a programmed value) with a current limit, which needs a low-ESR output capacitor COUT to GND for stable operation, with a 7 V absolute maximum. |
| 8 | NC | unconnected | Not connected. |
| 9 | WD_FLT | output | Watchdog fault output (active-low WD_FLT, TPS7A63-Q1 only) or latched active-high watchdog flag (WD_FLAG, TPS7A6401-Q1 only), each requiring an external pullup resistor to VOUT, with a 7 V absolute maximum. |
| 10 | WD | input | Watchdog service input that receives the service signal to the watchdog, with a recommended low-voltage range of 0 V to 5.25 V. |
| 11 | NC | unconnected | Not connected. |
| 12 | nWD_EN | input | Active-low watchdog enable input with an internal pulldown, where a high level disables the watchdog and a floating pin keeps it enabled, and the recommended range is 0 V to 5.25 V. |
| 13 | NC | unconnected | Not connected. |
| 14 | ROSC | output | Oscillator programming pin that sets the internal oscillator frequency and therefore the watchdog window through an external resistor to ground, referenced to a 7 V absolute maximum constant-voltage reference. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
