# 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. |
