LT8330ES6#TRMPBF from Analog Devices, in a TSOT-23-6. 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 | SW | passive | Output of the internal power switch (rated 60V max); minimize the metal trace area on this pin to reduce EMI. |
| 2 | GND | power_in | Ground connection for the LT8330; should be connected to a ground plane tied to large copper layers to spread dissipated heat. |
| 3 | FBX | input | Voltage regulation feedback pin for positive or negative outputs (regulates to 1.6V or -0.8V), connected to a resistor divider between the output and GND; reduces switching frequency when close to GND during start-up and faults. |
| 4 | EN/UVLO | input | Shutdown and undervoltage detect pin with accurate 1.6V falling threshold (1.68V rising, 80mV hysteresis); below 0.2V it reduces VIN current below 1µA, abs max 40V, and it can be tied to VIN if unused. |
| 5 | INTVCC | power_out | Regulated 3V supply for internal loads; must be bypassed with at least 1µF low-ESR ceramic capacitor to ground, cannot be externally driven and no additional loading is allowed. |
| 6 | VIN | power_in | Input supply pin (3V to 40V operating range) that must be locally bypassed, with the input capacitor placed as close as possible to VIN and GND. |
