LMR10515XMFX

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

LMR10515XMFX 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 Switch node that connects to the inductor and catch diode.
2 GND power_in Signal and power ground; the bottom resistor of the feedback network must be placed as close as possible to this pin.
3 FB input Feedback pin that connects to an external resistor divider to set the output voltage.
4 EN input Enable control input where logic high enables operation; it must not be left floating or be greater than VIN + 0.3 V.
5 VIN power_in Input supply voltage, 3 V to 5.5 V per the recommended operating ratings.
