LP3879MRX-1.0

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

LP3879MRX-1.0 from Texas Instruments, in a SOIC-8-EP. 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 BYPASS passive The capacitor connected between BYPASS and GROUND lowers output noise voltage and is required for loop stability.
2 N/C unconnected DO NOT CONNECT; this pin is used for post package test and must be left floating.
3 GROUND power_in Device ground.
4 INPUT power_in Input source voltage.
5 OUTPUT power_out Regulated output voltage.
6 SENSE input Remote sense; tie directly to output or remotely at point of load for best regulation.
7 N/C unconnected No internal connection.
8 SHUTDOWN input Output is enabled above the turn-on threshold voltage; pull down to turn off the regulator output.
9 SUBSTRATE power_in The exposed die attach pad should be connected to a thermal pad at ground potential.
