# LP2986IMMX-5.0

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · VSSOP-8-0.65mm

LP2986IMMX-5.0 from Texas Instruments, in a VSSOP-8-0.65mm. 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 | GROUND | power_in | Ground reference pin for the regulator. |
| 2 | FEEDBACK | input | Sets the output voltage: tie to TAP (with SENSE tied to OUT) for the fixed 5.0 V version, or drive it from an external resistor divider for an adjustable output; the FEEDBACK pin is rated -0.3 V to 5 V. |
| 3 | TAP | output | Middle tap of the internal voltage divider, which must be tied to FEEDBACK (with OUT tied to SENSE) to output the fixed voltage of the part version. |
| 4 | IN | power_in | Input voltage supply, specified from 2.1 V to 16 V operating. |
| 5 | OUT | power_out | Regulated output, rated for up to 200 mA output current. |
| 6 | SENSE | input | Connect to OUT (with FEEDBACK tied to TAP) to output the voltage of the part version. |
| 7 | ERROR | output | Active-low open-collector error output that goes low when VOUT drops about 5% below nominal, needs an external pull-up, and can sink up to 300 µA. |
| 8 | SHUTDOWN | input | Active-high enable input: pull it low to shut down the output; the pin is rated -0.3 V to 16 V. |
