LR8410B-TJ from LR, in a SOT-23-5L. 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 | VIN | power_in | Input voltage pin, rated for 7 V to 100 V continuous or transient input with a 110 V absolute maximum VIN. |
| 2 | GND | power_in | Ground pin, the common reference for the regulator. |
| 3 | EN | input | CMOS-compatible enable pin that turns the regulator on above 1.5 V and enters low-current shutdown below 0.4 V (ISD 8 µA typ, 15 µA max at VEN = 0 V). |
| 4 | FB | input | Feedback pin connected to the internal 0.8 V reference (0.788 V to 0.812 V) through the external divider, where VOUT = 0.8 V × (R1 + R2) / R2 and feedback pin current is 0.11 µA max. |
| 5 | VOUT | power_out | Regulated output voltage pin, adjustable from 1.2 V to 90 V and rated for up to 50 mA output current. |
