# L6982C50DR

**STMicroelectronics** · DC-DC Converters · SO-8

L6982C50DR from STMicroelectronics, in a SO-8. 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 | output | Switching node of the regulator; the datasheet gives no further limits for this pin. |
| 2 | BOOT | passive | Connect an external 100 nF (typ.) capacitor between BOOT and SW; the gate charge for the internal NMOS is refreshed during the low-side switch conduction time. |
| 3 | VCC | power_out | Supplies the embedded analog circuitry and needs a ceramic capacitor of at least 1 µF to filter the internal voltage reference. |
| 4 | FB/VOUT | input | FB is the output voltage sensing input, used with an external voltage divider. |
| 5 | EN/CLKIN | input | Enable pin with an internal voltage divider: pull down to disable and pull up to enable the device; in LNM versions it also accepts an external clock to synchronize the device. |
| 6 | AGND | power_in | Analog ground; the datasheet gives no further limits for this pin. |
| 7 | VIN | power_in | DC input voltage; the features list gives an operating input range of 3.5 V to 38 V. |
| 8 | PGND | power_in | Power ground; the datasheet gives no further limits for this pin. |
