# TPS78227QDRVRQ1

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

TPS78227QDRVRQ1 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 requiring a 1 μF ceramic capacitor from this pin to ground for stability. |
| 2 | NC | unconnected | Not connected. |
| 3 | GND | power_in | Ground pin; all ground pins must be tied to ground for proper operation. |
| 4 | EN | input | Enable pin; voltages above 1.2 V turn the regulator ON, below 0.4 V put it into shutdown mode reducing operating current to 18 nA typical. |
| 5 | GND | power_in | Ground pin; all ground pins must be tied to ground for proper operation. |
| 6 | IN | power_in | Input power supply pin requiring a 1.0 μF capacitor from this pin to ground; both input and output capacitor grounds should be tied back to the IC ground with minimal impedance. |
| 7 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
