TPS78222DRVR from Texas Instruments, in a WSON-6(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Regulated output voltage pin (2.2 V fixed, up to 150 mA). Requires a small 1-uF ceramic capacitor from this pin to ground to assure stability. |
| 2 | NC | unconnected | No internal connection. |
| 3 | GND | power_in | Ground pin. Tie all ground pins to ground for proper operation. |
| 4 | EN | input | Enable pin. Drive above 1.2 V to turn on the regulator. Drive below 0.4 V to put the regulator into shutdown mode, reducing operating current to 18 nA typical. CMOS-logic compatible. |
| 5 | GND | power_in | Ground pin. Tie all ground pins to ground for proper operation. |
| 6 | IN | power_in | Input pin (2.2 V to 5.5 V). For stable operation place a small 0.1-uF capacitor from this pin to ground; typical input capacitor = 1.0 uF. Tie back both input and output capacitor grounds to the IC ground with no significant impedance between them. |
| 7 | Thermal Pad | passive | Exposed thermal pad on the bottom of the SON-6 package. Connect the thermal pad to ground for thermal dissipation and electrical grounding. |
