TPAPL3511ABI-TRG

TECH PUBLIC · Power Distribution Switches · SOT-23-5

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.
