LP38853S-ADJ from Texas Instruments, in a TO-263-7. 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 | SS | output | Soft-start capacitor connection, used to control the rise time of VOUT at turnon. |
| 2 | EN | input | Device enable, High = On, Low = Off; the datasheet gives the EN voltage range as 0 to VBIAS. |
| 3 | IN | input | The unregulated voltage input; the datasheet limits VIN to no more than the lower of VBIAS or 4.5 V. |
| 4 | GND | power_in | Ground pin. |
| 5 | ADJ | output | The feedback connection used to set the output voltage, with adjustable VOUT range of 0.8 V to 1.8 V. |
| 6 | OUT | output | The regulated output voltage. |
| 7 | BIAS | input | The supply for the internal control and reference circuitry, specified at 3 V to 5.5 V. |
| 8 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
