LP5907QMFX-3.0Q1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

LP5907QMFX-3.0Q1 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 IN power_in Input voltage supply for regulated 250mA output, operating range 2.2V to 5.5V, requires minimum 1µF input capacitor.
2 GND power_in Common ground reference for all pins.
3 EN input Enable logic input; device enabled when voltage > 1.2V (VIH), disabled when voltage < 0.4V (VIL), with internal 1MΩ pulldown resistor holding device off by default.
4 N/C unconnected No internal electrical connection.
5 OUT output Regulated output voltage (3.0V fixed for this MPN variant) with 250mA source capability, internal 230Ω pulldown resistor discharges output through this pin when device is disabled, requires minimum 1µF low-ESR output capacitor.
