# LP2986AIMM-3.3

**Texas Instruments** · Linear Voltage Regulators (LDO) · VSSOP-8-0.65mm

LP2986AIMM-3.3 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 OUT tied to SENSE) for the fixed version, or connect to a resistor divider for an adjustable output; the FEEDBACK pin is rated for a maximum of 5 V (absolute maximum, -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, with an operating supply range of 2.1 V to 16 V. |
| 5 | OUT | power_out | Regulated output, which supplies up to 200 mA and must be tied to SENSE for the fixed-voltage configuration. |
| 6 | SENSE | input | Output sense input, which is connected to OUT (with FEEDBACK tied to TAP) so the output voltage of the part version is regulated at the load. |
| 7 | ERROR | output | Active-low open-collector error flag that goes low when VOUT drops about 5% below nominal, sinking up to 300 µA and requiring an external pull-up to 16 V maximum. |
| 8 | SHUTDOWN | input | Active-high shutdown input: pull low to turn the output off, with a maximum rating of 16 V (-0.3 V to 16 V absolute maximum). |
