# TPS78225QDRVRQ1

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6-EP(2x2)

TPS78225QDRVRQ1 from Texas Instruments, in a WSON-6-EP(2x2). 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 | OUT | power_out | Regulated output voltage pin that needs a small (1 μF) ceramic capacitor from this pin to ground to assure stability. |
| 2 | NC | unconnected | Not connected. |
| 3 | GND | power_in | All ground pins must be tied to ground for proper operation. |
| 4 | EN | input | Driving EN above 1.2 V turns the regulator on and driving it below 0.4 V puts the regulator into shutdown, reducing operating current to 18 nA typical; EN must not exceed VIN + 0.3 V. |
| 5 | GND | power_in | All ground pins must be tied to ground for proper operation. |
| 6 | IN | power_in | Input pin that needs a small capacitor to ground for stability (typical 1.0 μF); input voltage range is 2.2 V to 5.5 V. |
| 7 | Thermal Pad | power_in | Thermal pad that is recommended to be connected to ground and soldered to the PCB for thermal and mechanical performance. |
