LM27313XQMFX

Texas Instruments · DC-DC Converters · SOT-23-5

LM27313XQMFX 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 SW output Drain of the internal FET switch with maximum voltage rating of 30 V.
2 GND power_in Analog and power ground.
3 FB input Feedback point that connects to external resistive divider to set VOUT with voltage range −0.4 to 6 V.
4 SHDN input Shutdown control input with recommended voltage range 0 to VIN; connect to VIN if this feature is not used.
5 VIN power_in Analog and power input with recommended operating voltage range 2.7 to 14 V.
