LMR10510XMFX

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

LMR10510XMFX 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 output with internal 130 mΩ PMOS on-resistance; drives external inductor and catch diode in buck topology; absolute maximum voltage -0.5V to 7V.
2 GND power_in Signal and power ground return pin; place bottom resistor of feedback network divider as close as possible to this pin.
3 FB input Feedback voltage input for external resistor divider to set output voltage; nominal reference voltage 0.6V; input bias current 0.1 to 100 nA; absolute maximum -0.5V to 3V.
4 EN input Enable control input; logic high enables operation; do not allow to float or exceed VIN + 0.3V; enable threshold 1.8V, shutdown threshold 0.4V; absolute maximum -0.5V to 7V.
5 VIN power_in Power supply input voltage; recommended operating range 3V to 5.5V; quiescent current 3.3 to 5 mA for LMR10510X (1.6MHz switching frequency); absolute maximum -0.5V to 7V.
