TPS7A1112PDRVR 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 pin capable of 500mA maximum output current; requires 2.2µF to 22µF ceramic capacitor (ESR < 250mΩ) to ground for stability. |
| 2 | NC | unconnected | No internal connection; may be connected to ground for improved thermal dissipation or left floating. |
| 3 | EN | input | Enable input (active high); device enables when EN > 0.9V and disables when EN < 0.4V. |
| 4 | BIAS | power_in | Bias power supply input with 1.7V to 5.5V operating range; requires 0.1µF ceramic capacitor to ground and exhibits 0.85V to 1.2V dropout voltage at 500mA output current. |
| 5 | GND | power_in | Ground return pin; must be connected to ground, and exposed thermal pad must be connected to large-area ground plane for thermal management. |
| 6 | IN | power_in | Input power supply pin with 0.75V to 3.3V operating range; requires 2.2µF ceramic capacitor to ground for stability and exhibits 90mV to 140mV dropout voltage at 500mA. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
