TPAPL3511ABI-TRG from TECH PUBLIC, 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 | VOUT | power_out | Output Voltage Pin. The output voltage follows the input voltage. When ENB is high or EN is low, the output voltage is discharged by an internal resistor. |
| 2 | GND | power_in | Ground. Return path for supply current; connect to system ground plane. |
| 3 | OCB | output | Open-Drain Fault Indication Output. Goes low when a current-limit or over-temperature condition is detected after a 12 ms deglitch time; requires external pull-up resistor. |
| 4 | EN | input | Enable Input. Pulling high (≥1.3 V) enables the device; pulling low (<0.7 V) disables it; pin cannot be left floating; compatible with TTL and CMOS logic levels. |
| 5 | VIN | power_in | Power Supply Input. Connect to external DC supply in the range 2.5 V to 5.5 V (abs max 6.5 V); supports soft-start to limit inrush current. |
