LP2982IM5X-5.0

Texas Instruments · Linear Voltage Regulators (LDO) · SOT-23-5

LP2982IM5X-5.0 from Texas Instruments, in a SOT-23-5. 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 IN power_in Input voltage pin supplying the regulator; the datasheet lists it only as 'Input voltage' with no separate limits on this page.
2 GND power_in Common ground pin, connected to the device substrate.
3 ON/OFF input Logic high enable input that turns the regulator on when pulled high and places it in shutdown when pulled low.
4 BYPASS bidirectional Bypass capacitor connection for low-noise operation, used as an input/output pin.
5 OUT power_out Regulated output voltage pin.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper On the LP2982 SOT-23 (DBV) package, the primary conduction path for heat is through the five leads to the PCB. The ground pin (pin 2) is attached directly to the back side of the die and should be acc 18
