LP3982IMMX-1.8 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 | output | Regulated output voltage supporting maximum load current of 300 mA with ±2% output voltage tolerance. |
| 2 | IN | power_in | Input supply voltage ranging from 2.5 V to 6 V with dropout voltage from 0.4 mV at 1 mA to 120 mV at 300 mA. |
| 3 | GND | power_in | Ground reference connection. |
| 4 | OUT | output | Regulated output voltage supporting maximum load current of 300 mA with ±2% output voltage tolerance. |
| 5 | SET | unconnected | Output voltage adjustment pin (internally disconnected and non-functional in this fixed 1.8 V version). |
| 6 | CC | passive | Noise bypass capacitor connection to ground with optimum value of 33 nF achieving 37 μVRMS output noise (10 Hz to 100 kHz). |
| 7 | SHDN | input | Shutdown control input with logic threshold VIH 2 V to enable and VIL 0.4 V to disable, drawing 1 nA typical in shutdown. |
| 8 | FAULT | output | Active-low open-drain fault detection output asserting during over-current condition (330 mA limit), thermal shutdown (160°C typical), or dropout approach. |
