TLV73311PQDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 | Supply input pin rated for 1.4 V to 5.5 V operation with bypass capacitor recommended for stability. |
| 2 | GND | power_in | Ground reference pin; electrically connected to thermal pad and ground plane for thermal performance. |
| 3 | EN | input | Enable input (active high); drive > 0.9 V to enable regulator, < 0.35 V to disable with 120 Ω pulldown for output discharge. |
| 4 | NC | unconnected | No internal connection; pin can be left floating or connected to ground. |
| 5 | OUT | power_out | Regulated 1.1 V output rated for 300 mA maximum source current; 0.51 V maximum dropout voltage at full load. |
