LP5912-3.0DRVR 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; the device supplies up to 500 mA with a fixed output from 0.8 V to 5.5 V. |
| 2 | NC | unconnected | No internal connection; leave open, or connect to ground. |
| 3 | PG | output | Power-good open-drain indicator that requires an external pullup, typically 10 kΩ to 100 kΩ, and whose status is undefined when VIN is below 1.6 V. |
| 4 | EN | input | Enable input; logic high turns the device on and logic low turns it off, with an internal 3-MΩ pulldown to GND. |
| 5 | GND | power_in | Ground. |
| 6 | IN | power_in | Unregulated input voltage with a recommended supply range of 1.6 V to 6.5 V. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
