TPS7B8333QDCYRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

TPS7B8333QDCYRQ1 from Texas Instruments, in a SOT-223-4. 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 power_in Input supply pin with a recommended operating range of 3 V to 40 V (42 V absolute maximum), using a 0.1 µF to 1 µF ceramic input capacitor (minimum 500 nF for EMI) placed as close to the pin as possible.
2 GND power_in Ground pin that must be connected to the thermal pad with a low-impedance connection.
3 OUT power_out Regulated 3.3 V output that requires an output capacitor to ground for stability, with at least 1 µF effective capacitance and a recommended COUT range of 2.2 µF to 220 µF, placed as close to the pin as possible.
4 GND power_in Ground pin that must be connected to the thermal pad with a low-impedance connection.
