TEXAS INSTRUMENTS · Global Sourcing Parts · SOT-23-5

TPS7B92033DBVR from TEXAS INSTRUMENTS, 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 IN input Input power supply pin; the recommended VIN range is 2.5 V to 40 V, and input capacitor requirements are given in the datasheet.
2 GND power_in Ground pin.
3 NC unconnected No internal connection; keep this pin floating or connect it to any potential, and connect it to ground to improve thermal performance.
4 NC unconnected No internal connection; keep this pin floating or connect it to any potential, and connect it to ground to improve thermal performance.
5 OUT output Regulator output; the recommended VOUT range is 1.2 V to 12 V, with output current up to 300 mA.
