LP5907QMFX-2.5Q1

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

LP5907QMFX-2.5Q1 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 with operating range 2.2 V to 5.5 V; requires 1 µF capacitor connection at this pin.
2 GND power_in Common ground pin.
3 EN input Enable input with logic low threshold VIL = 0.4 V (disables regulator) and high threshold VIH = 1.2 V (enables regulator); 1 MΩ internal pulldown resistor to GND.
4 N/C unconnected No internal electrical connection.
5 OUT power_out Regulated output voltage of 2.5 V nominal with maximum 250 mA output current; requires minimum 1 µF low-ESR capacitor connection; 230 Ω pulldown resistance when EN is low.
