TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
TPLP2981-50DBVR from TECH PUBLIC, 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 | VIN | power_in | Input of supply voltage, 2 V to 18 V operating supply range (absolute maximum 18 V). |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable control input; rising threshold 1.1 V min, falling threshold 0.4 V max, absolute maximum 18 V. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Output of the regulator, 5.0 V fixed for the -50 option, up to 100 mA output current. |
