LP3874EMP-5.0

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-5

LP3874EMP-5.0 from Texas Instruments, in a SOT-223-5. 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 SD input Shutdown control input; pull HIGH for normal operation, pull LOW for shutdown with 10-nA quiescent current.
2 IN power_in Input supply voltage from 2.5 V to 7 V.
3 OUT power_out Regulated 5.0 V output with ±1.5% accuracy at room temperature and ±3% over all conditions, supporting up to 0.8 A DC output current.
4 SENSE input Remote voltage sense input for improved load regulation; connection is optional for remote load sensing.
5 GND power_in Ground connection; ground pin current is typically 6 mA at 0.8 A load current.
