TPLP2981-28DBVR

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPLP2981-28DBVR 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, pin voltage range -0.3 V to 18 V.
4 NC unconnected No internal connection.
5 VOUT power_out Output of the regulator (2.8 V for the -28 option), up to 100 mA with internal current limit.
