LP3981IMMX-2.5

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

LP3981IMMX-2.5 from Texas Instruments, in a VSSOP-8. 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 Output voltage of the LDO.
2 IN power_in Input voltage of the LDO.
3 NC unconnected No internal connection.
4 OUT-SENSE output Output voltage sense pin; must be connected to OUT for proper operation.
5 GND power_in Common ground; connect to PAD.
6 BYPASS passive Optional bypass capacitor for noise reduction.
7 EN input Enable input logic, enable high.
8 NC unconnected No internal connection.
