# LP3982IMMX-ADJ

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

LP3982IMMX-ADJ 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 | OUT | power_out | Regulated output voltage with maximum 300-mA output current and 120-mV typical dropout voltage. |
| 2 | IN | power_in | Input supply voltage to the regulator; supply range is 2.5 V to 6 V. |
| 3 | GND | power_in | Ground reference. |
| 4 | OUT | power_out | Regulated output voltage with maximum 300-mA output current and 120-mV typical dropout voltage. |
| 5 | SET | input | Resistor divider input for setting output voltage in the adjustable version (voltage range −0.3 to 6.5 V); internally disconnected in fixed versions. |
| 6 | CC | passive | Noise compensation capacitor connection pin; connect 33-nF capacitor to ground for optimal output noise reduction (voltage range −0.3 to 6.5 V). |
| 7 | SHDN | input | Shutdown control input; pull high for ON state or low for OFF state (voltage range −0.3 to 6.5 V). |
| 8 | FAULT | output | Active-low open-drain fault output that indicates out-of-regulation conditions including current limit, thermal shutdown, or approaching dropout (maximum sink current 20 mA); requires pullup resistor (voltage range −0.3 to 6.5 V). |
